Dynamic Photoelastic and Dynamic Finite Element Analyses of Dynamic Tear Test Specimens.

Abstract

Dynamic photoelasticity and dynamic finite element methods were used to study the transient response of dynamic tear test (DTT) specimen of a brittle material Homalite-100. The dynamic stress intensity factors obtained from dynamic photoelasticity and dynamic finite element analysis were generally in excellent agreement with each other and showed that the NRL procedure of computing the dynamic fracture initiation thoughness from strain gage measurements near the velocity relations were also obtained.
