Characterization Of Polyetherimide Under Static, Dynamic, And Multiple Impact Conditions, Bryan Zuanetti
Characterization Of Polyetherimide Under Static, Dynamic, And Multiple Impact Conditions, Bryan Zuanetti
HIM 1990-2015
The application of polymers in robust engineering designs is on the rise due to their excellent mechanical properties such as high fracture toughness, specific strength, durability, as well as, thermal and chemical resistances. Implementation of some advanced polymeric solids is limited due to the lack of available mechanical properties. In order for these materials to endure strenuous engineering designs it is vital to investigate their response in multiple loading rates and conditions. In this thesis, the mechanical response of polyethermide (PEI) is characterized under quasi-static, high strain rate, and multiple impact conditions. Standard tension, torsion, and compression experiments are performed …
