Design Treatment for Advanced Metals Enables Easier Machining

  • Magazine Article
  • TBMG-35802
Published 2020-01-01 by Tech Briefs Media Group in United States

Exotic and advanced metals are used in aircraft, orthopedic components, medical instruments, cars, solar panels, military equipment, and other applications. They are referred to as advanced or exotic because they are more difficult to find and more costly to use in manufacturing.

Dynamic Mechanical Strain-Induced Temperature Gradient Coating

  • Magazine Article
  • TBMG-35811
Published 2020-01-01 by Tech Briefs Media Group in United States

Evaluating components for discontinuities without damaging the part or system remains a priority for diverse industries and research fields. Low-cost techniques such as fluorescent penetrant inspection (FPI) are used widely by major industries, such as aviation and aerospace, despite limited defect detection and the need for complex, multi-step operations in highly controlled conditions. Nondestructive methods such as sonic infrared (SIR) testing apply ultrasound waves to identify surface defects and cracks. These techniques hold promise for widespread use but stand to improve in the detection of false positives.

The Three Rs of Analog Position Sensor-Based Mechanical Measurements

  • Magazine Article
  • TBMG-35681
Published 2019-12-01 by Tech Briefs Media Group in United States

Those of us old enough to remember the “good old days” recall that grade school focused on learning the 3 R's: reading, ‘riting, and ‘rithametic. In the world of sensors, there are also 3 R's: Repeatability, Resolution, and Response. As important as these sensor parameters are, there is often confusion in the mind of users about exactly what they mean and in what ways they tend to interact with each other. This article will attempt to explain the 3 R's for position sensors and dispel any confusion that might exist.

Molecular Engineering for Mechanically Resilient and Stretchable Electronic Polymers and Composites

  • Magazine Article
  • TBMG-35664
Published 2019-12-01 by Tech Briefs Media Group in United States

The ability to predict the mechanical properties of organic semiconductors is of critical importance for roll-to-roll production and thermomechanical reliability of organic electronic devices. This research describes the use of coarse-grained molecular dynamics simulations to predict the density, tensile modulus, Poisson ratio, and glass transition temperature for poly(3-hexylthiophene) (P3HT) and its blend with C60. In particular, it is shown that the resolution of the coarse-grained model has a strong effect on the predicted properties.

The Role of Sensors in the Evolution of Robotics

  • Magazine Article
  • TBMG-35609
Published 2019-12-01 by Tech Briefs Media Group in United States

At one time, robotics was considered more science fiction than reality. That's changing. Today, robots are increasingly playing a role in our everyday lives. They're zooming around our homes to pick up dust, helping surgeons perform operations with even more precision, sniffing out suspicious packages for law enforcement, and on the factory floor, they're performing all kinds of tasks for automotive, electronics, and industrial manufacturing companies.

Technology Impact Forecasting for Multi-Functional Composites

  • Magazine Article
  • TBMG-35679
Published 2019-12-01 by Tech Briefs Media Group in United States

To survive within today's stringent economic environment, aircraft design, particularly military aircraft design, has been experiencing a paradigm shift from an emphasis on design for optimum performance to design for system effectiveness. As a consequence, designers and manufacturers are increasingly considering the addition of new technologies to aircraft design to reduce their cost, increase their operating capacities, and optimize new capabilities.
