Abstract

The stress response of axially constrained two-layer composite tubes under cyclic loading of external pressure is investigated in this study. Elastic and elastoplastic stress states for the tube assemblies are examined by developing a mathematical model based on Tresca's yield criterion, its associated
ow rule, and linear strain hardening. Using this model, the composite tubes with different dimensions are analyzed under one cycle of loading, unloading, and reloading of external pressure. It is observed that the elastic limit for the plastically predeformed tube assembly is higher than that for the undeformed one, just like the tubes subjected to internal pressure.

Keywords: Elastoplasticity, tresca criterion, strain hardening, cyclic loading
