Abstract:

Photoplasticity and photoelastic coating techniques have been successfully employed to study stress concentration in the elastoplastic state and residual stress after unloading. Principles are described herein, and examples of the application of both methods are given. The results show that stress concentration in the elastoplastic state is lower than that in the elastic state and decreases continuously as yielding progresses. A good agreement exists between results from both methods.
