Procedure Qualification Scheme Portfolio for Metal Directed Energy Deposition Additive Manufacturing

2024-01-3929

11/15/2024

ABSTRACT Standard requirements for directed energy deposition (DED) additive manufacturing (AM) of parts were needed for a new NAVSEA Technical Publication. DED procedure qualification schemes were developed for integrated and non-integrated build platforms and for both single-sided and double-sided build applications. A double-sided build platform approach is widely preferred for distortion control and build productivity. These procedure qualification requirements were developed for arc, laser, and electron beam welding-based DED processes using wire or powder consumables. Each procedure qualification scheme included a standard qualification build (SQB) design, nondestructive evaluation test map, property specimen test matrix and qualification records for each application and process combination. Since these metal AM processes cover a range of feature size capabilities that are defined by minimum deposit bead width, SQBs were designed for full-scale (~> 5 mm), sub-scale (~2 – 5 mm

FINITE ELEMENT OPTIMIZATION FOR NONDESTRUCTIVE EVALUATION ON A GRAPHICS PROCESSING UNIT FOR GROUND VEHICLE HULL INSPECTION

2024-01-3430

11/15/2024

ABSTRACT Shape reconstruction for nondestructive evaluation (NDE) of internal defects in ground vehicle hulls using eddy current probes provides a rationale for determination of when to withdraw vehicles from deployment. This process requires detailed finite element optimization and is computationally intensive. Traditional shared memory parallel systems, however, are prohibitively expensive and have limited central processing units (CPUs), making speedup limited. So parallelization has never been done. However, a CPU that is connected to graphics processing units (GPUs) with effective built-in shared memory provides a new opportunity. We implement the naturally parallel, genetic algorithm (GA) for synthesizing defect shapes on GPUs. Shapes are optimized to match exterior measurements, launching the parallel, executable GA kernel on hundreds of CUDA™ (Compute Unified Device Architecture) threads to establish the efficiencies

ENHANCED BLAST PROTECTION WITH POLYMER COMPOSITES CONTAINING XGNP^® GRAPHENE NANOPLATELETS

2024-01-3640

11/15/2024

ABSTRACT Fiber reinforced thermoset composites are well known for delivering 50% or more weight savings when compared with steel components while also providing strength, stiffness, and toughness. Nanoparticle additives have been shown to significantly increase the mechanical properties of thermoplastic and thermoset polymer matrices over the base matrix values. Extensive testing and characterization of composites containing graphene nanoplatelets (GnP) has been conducted and reported by XG Sciences’ (XGS) collaborators at the Michigan State University (MSU) Composite Materials and Structures Center. In a recent program with U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC), MSU investigated lightweight composites for blast and impact protection. High strain rate test facilities as well as high speed photography and non-destructive interferometry-based evaluation techniques were used to evaluate blast performance. The experimental results are presented

NON-DESTRUCTIVE TESTING OF SENSOR ENHANCED ARMOR

2024-01-3236

11/15/2024

ABSTRACT The US Army is replacing conventional armor with new types of ballistic protection which are lighter in weight than the materials they replace yet offer the same degree of protection. A key component of this new type of armor is called Multi Functional (MFA) or Sensor Enhanced Armor (SEA) because the armor provides more capabilities than traditional ballistic protection for the soldier and ground vehicle. In this paper we shall concentrate on the real-time health monitoring of SEA. We have developed a method which has been applied to several types of new ballistic protection. We use ultrasonic waves to excite the armor panel. We measure the response to the excitation when the ballistic protection is known to be undamaged and store the results in a database. To determine if the armor has been damaged, we measure it again and compare the new results to the contents of the database

Detection of Cut-Out in Aluminum Plate Using Ultrasonic Guided Waves: A Finite Element Analysis

01-17-03-0019

11/09/2024

Aluminum alloys serve a critical role in the aerospace industry, accounting for a significant amount of commercial aircraft weight. Despite the growing use of composite materials, aluminum remains important in airframe construction due to its lightweight, cost-effectiveness, and high strength potential. Structural integrity is critical in modern engineering, necessitating early diagnosis and localization of damage. To detect the flaws, cracks, and cut-out in the structures, structural health monitoring (SHM) systems are essential, with non-destructive testing (NDT) methodologies playing critical roles. Among these technologies, ultrasonic guided wave testing (UGWT) has gained popularity because of its capacity to propagate over long distances and detect subsurface faults. This article investigates the use of UGWs to identify cut-outs in aluminum plates. The numerical investigation has been carried out using commercially available finite element software Abaqus. The ultrasonic lamb

Automatic Switching for Radiation Emission Control Device in Radiographic Testing – Non-Destructive Testing

2023-01-5108

02/23/2024

In radiography testing, the radioactive elements Iridium 192 (Ir192) and Cobalt 60 (Co60) are employed to detect subsurface and inner flaws. These radioactive components are kept secure within the radiation-protected source camera. Despite the fact that the camera is safe, there is a little quantity of radiation that may harm human body cells. In this present study, it restricts radiation emission by placing a lead sheet over the source camera, which absorbs the produced radiation. The innovative concept involves in this present work is to place a manually operated switch near the radiation source to emit radiation

The Neutronic Engine: A Platform for Operando Neutron Diffraction in Internal Combustion Engines

03-17-02-0016

11/09/2023

Neutron diffraction is a powerful tool for noninvasive and nondestructive characterization of materials and can be applied even in large devices such as internal combustion engines thanks to neutrons’ exceptional ability to penetrate many materials. While proof-of-concept experiments have shown the ability to measure spatially and temporally resolved lattice strains in a small aluminum engine on a timescale of minutes over a limited spatial region, extending this capability to timescales on the order of a crank angle degree over the full volume of the combustion chamber requires careful design and optimization of the engine structure to minimize attenuation of the incident and diffracted neutrons to maximize count rates. We present the design of a “neutronic engine,” which is analogous to an optical engine in that the materials and external geometry of a typical automotive engine have been optimized to maximize access of the diagnostic while maintaining the internal combustion chamber

Non-destructive evaluation of aircraft production is optimized and digitalized with Industry 4.0. The aircraft structures produced using fiber metal laminate are traditionally inspected using water-coupled ultrasound scans and manually evaluated. German Aerospace Center (DLR), Augsburg, Germany Ultrasonic Testing (UT) is a typical Non-destructive testing (NDT) method for examining the structural components for aircraft production. Manufacturing aircraft made of fiber metal laminates (FML) includes cascaded steps such as placement of aluminum, glass prepreg, adhesive, doublers, stringers, vacuum bagging and curing in an autoclave. Quality control (QC) is performed first at the layup of the component (without stringers) after curing and the quality assessment is visually evaluated. The manually performed examination of anomalies is very time-consuming.

Development of Digital Shearography for Dual Sensitivity Simultaneous Measurement Using Carrier Frequency Spatial Phase Shift Technology

2023-01-0068

04/11/2023

Digital shearography has many advantages, such as full-field, non-contact, high sensitivity, and good robustness. It was widely used to measure the deformation and strain of materials, also to the application of nondestructive testing (NDT). However, most digital sherography applications can only work in one field of view per measurement, and some small defects may not be detected as a result. Multiple measurements of different fields of view are needed to solve this issue, which will increase the measurement time and cost. The difficulty in performing multiple measurements may also increase for cases where the loading is not repeatable. Therefore, a system capable of measuring dual fields of view at the same time is necessary. The carrier frequency spatial phase shift method may be a good candidate to reach this goal because it can simultaneously record phase information of multiple images, e.g. two speckle interferograms with different fields of view. It then obtains the phase

In Line Nondestructive Testing for Sheet Metal Friction Stir Welding

2023-01-0069

04/11/2023

As automotive designs add more aluminum to lightweight their vehicles, friction stir welding (FSW) will likely become a principal joining process in the industry. FSW is a solid-state joining process which avoids many of the traditional problems of welding aluminum alloys such as hot cracking, porosity and solidification shrinkage. These attributes enable high preforming friction stir welded joints of cast, 5XXX, 6XXX, 7XXX or mixed aluminum alloy combinations. Although FSW technologies have advanced to support high volume applications and have been applied in current automotive parts, its inability for nondestructive evaluation (NDE) increases the cost to manufacture friction stir welded parts. Current state of the art NDE methods for FSW are either ultrasound or radiographic technologies which add complexity to manufacturing lines and additional costs to FSW production. Many have researched ways to reduce NDE costs by using measured forces of the FSW process. These methods have

Modernization of Equipment in Aerospace Nondestructive Inspection

2023-01-1007

03/07/2023

Equipment used in aerospace non-destructive inspection presents opportunity for modernization. Many inspection cells in production operate using a widely available control system software that is suitable for most inspection applications with minimal customization. The size and complex geometry of airframe components demand more application-specific system design to ensure the reliability and cycle time required for an aerospace production schedule. Ordinary inspection systems require manual teaching for program generation and lack datum-finding systems required to rerun programs without modification. Integration of offline programming software and machine vision instruments can save inspection technicians hours or shifts per part by eliminating the need for program retraining due to variation in part delivery position. Modernized inspection cells will reduce labor burden on technicians and provide reliable cycle time information to production planners
