Finite Element Method: An Introduction

  • S. I. Krishnamachari


The major change that occurred in the 1980s in the field of plastics parts design was the introduction of the stress analysis of components as a formal activity. This has led to a change in the profile of the design engineer, who in addition to having to perform the hitherto routine material selection, quantity estimation, fabrication drawing production, now needs to be a stress analyst too. It is about the only engineering field that is distinctly technical, and needs specialized knowledge. Having discussed earlier the stress categories and their significance at length, it is clear that the finite element stress analysis cannot be used as a black box, notwithstanding the way such software packages are marketed. The current generation of plastics designers do experience difficulty when working with finite elements, simply because of the different engineering discipline in which they have experience. Also, it is a matter of computational insight to determine what factors of material behavior are significant in what types of problems.
