Material Selection Based on Performance [chapter]

Eric R. Larson
2015 Thermoplastic Material Selection  
The ultimate goal of effective material selection is to optimize the performance of the product itself. While this may seem like a trivial statement, it is an important one.  ...  Material selection is a difficult task. Regardless of whether the material in question is wood, metal, stone, or plastic, selecting the proper material for a given application is a complex process.  ...  There are a number of methods of doing this. A common means is structural analysis using the finite element method. This type of analysis is well suited for identifying areas of high stress.  ...
