Calculation of the local critical state taking into account the deterioration and the residual stresses

Abstract

The critical state of structures simultaneous loaded with different loads is analised taking into account the principle of critical energy. The general case is considered when the material behavior is non-linear according to the power law. The critical state is correlated with the deterioration produced by cracks and with the residual stresses. General relationships have been deduced for the correlation of loads or stresses acting on a cracked structure having residual stresses. The theoretical relationships were verified against results reported in literature.
