FEA Beyond Basics: Nonlinear Analysis

Finite Element Analysis (FEA) has been an indispensable tool for design simulation for several decades but this wide spread use has been limited to simple types of analyses. Relatively recently, more advanced analyses have given easy to use interfaces enabling design engineers to simulate problems formerly reserved for analysts. This three-session web seminar targets the FEA users who wish to explore those advanced analysis capabilities.

The course demonstrates how to move past the ubiquitous linear structural analysis and solve structural nonlinear problems characterized by nonlinear material, large displacements, buckling or nonlinear connectors. The discussion will help participants identify, set up and solve complex nonlinear problems and as well as use results of nonlinear analysis to support the product design process.

All topics are illustrated using FEA software, SolidWorks® Simulation, for which participants will be provided a student license (compatible with 64-bit Windows 7 SP1, 8.1, 10; IE 10,11; MS Excel and Word 2010, 2013, 2016) and opportunity to practice skills learned. Acquired skills, however, will not be software specific and no prior exposure to FEA software is required. In-class, hands-on exercises and between-session assignments will provide an opportunity to put what is learned into practice.

What Will You Learn

By participating in this web seminar, you will be able to:
  • Identify a need for a nonlinear structural analysis
  • Identify the types of nonlinearities
  • Employ correct problem definition and solution strategy
  • Select applicable modeling techniques
  • Assess and implement results of nonlinear analysis

Is This Course For You

The course is intended for design engineers who already have a foundational understanding of FEA but need to elevate its use to an advanced level to predict product behavior more closely. Familiarity or experience with FEA equivalent to or as covered in the Finite Element Analysis for Design Engineers web seminar (WB1241) or Finite Element Analysis for Design Engineers on-demand course (PD531241) is recommended.
