The Finite Element Analysis FEA Workshop Module

SUMMARY

The Finite Element Analysis (FEA) has been widely implemented by automotive companies and is used by design engineers as a tool during the product development process. Design engineers analyze their own designs while they are still in the form of easily modifiable CAD models to allow for quick turnaround times and to ensure prompt implementation of analysis results in the design process. While FEA software is readily available, successful use of FEA as a design tool still requires an understanding of FEA basics, familiarity with FEA process and commonly used modeling techniques, as well as an appreciation of inherent errors and their effect on the quality of results. When used properly, the FEA becomes a tremendous productivity tool, helping design engineers reduce product development time and cost. Misapplication of FEA however, may lead to erroneous design decisions, which are very expensive to correct later in the design process.

Learning Objectives

  • Select preferable modeling approaches
  • Analyze errors inherent to FEA results
  • Identify FEA advantages and shortcomings
  • Avoid mistakes and pitfalls in FEA
  • Produce reliable results on time
  • Request FEA analysis and use FEA results
