Dynamic Behaviour of Solids Clarified by High Speed Photoelasticity

  • Kozo Kawata

Abstract

The main five cases of dynamic behaviour of solids clarified by high speed photoelasticity in Kawata’s laboratory with my colleagues since 1965 are stated, including both historical review and results obtained recently. They reveal the superior character of photoelasticity as visualization and analysis method of dynamic behaviour of solids, such as stress concentration, plastic region propagation front, etc., in both elastic and plastic states, differing remarkably from the corresponding static behaviour.
