Coupled Processes of Deformation and Long-Term Damage of Physically Nonlinear Laminated Materials

A theory of long-term damage of laminated materials with physically nonlinear components is proposed. The damage of components is modeled by random micropores. The damage criterion for a microvolume is characterized by its stress-rupture strength. It is determined by the dependence of the time to brittle failure on the difference between the equivalent stress and its critical value, which is the tensile strength, according to the Huber–Mises...
