TL;DR: In this paper, a simple description of the ratchetting properties of copper, as a typical strain hardening material, is proposed and used to predict the strain growth of a copper wire subject to simulated cyclic thermal loading using a novel experimental technique.

TL;DR: In this article, the results of experiments on 2-bar structures of 99.9% copper are compared with the prediction of classical plasticity models for loading histories which simulate the effects of thermal cycling in the presence of constant primary loading.

TL;DR: In this paper, upper bounds on the rupture life and time to initial rupture of a body obeying the Katchanov creep rupture equations are derived for cyclic load and temperature, without reference to the deformation properties.

TL;DR: In this article, a set of creep experiments conducted on 316 austenitic stainless steel in a coupled pair of uniaxial creep testing machines which simulate the performance of a two bar structure subjected to constant mechanical and cyclic thermal loading in the temperature range of 550-600°C.

TL;DR: In this paper, the behavior of a simple two bar structure subjected to cyclic thermal loading is investigated both experimentally and theoretically for transitional conditions between creep and plasticity, using copper as a model strain-hardening material.
