As Finite Element Analysis (FEA) within CAD environments has become increasingly commonplace in today’s engineering office, there is a greater demand to understand the types of analysis that can be conducted.
Having an understanding of non-linear analysis and when to use it helps designers simulate product performance and optimise designs.
FEA is a computational technique for verifying the structural integrity of components. It provides a greater understanding of how a product works, optimisation of current designs, and validation of ‘what if’ scenarios, which in turn lead to greater innovation and development.
Failure to account for non-linear behaviour, in large deformations and/or inelastic material behaviour, can lead to product failures, safety issues, and unnecessary cost to product manufacturers.
This white paper highlights the differences between linear and non-linear analysis from the point of view of a practical application, and can benefit designers who are looking to further their knowledge in FEA.
We look at non-linear analysis performed using Autodesk Nastran and Simulation Mechanical FEA software, and explore when to use non-linear versus linear analysis. This paper also covers the differences between these analyses, the importance of using the correct analysis type, and the risk posed from running an incorrect type of analysis.
