Firstly, it is a basic problem. I need to decide on a part of machine or anything for material selection presentation using CES Material Selector. I need a simple shape and simple property material because I can't calculate complicate dynamic loading so I need some limitations for instance, elongation, elastic modulus, base material,composition detail, price, density, mechanical, thermal ,electrical, optical properties etc.(they are surely as range). I did my last project on shoe middle and outer sole for walking shoes but it was hard to find specific infos. The material should be very specific using because determining of limitatons based on that. Which material is the most suitable for this situation? Thanks a lot.
