Abstract
This paper presents ultimate compressive strength of hot-rolled stainless clad steel plates and their residual stress distribution in the direction of thickness. Distribution of the residual stress is analytically given by simulating the cladding process, and modeled based on the analytical results as well as experimental results. Lastly, the ultimate compressive strength of clad plates simply supported around is obtained by elastoplastic nonlinear analyses, considering with the residual stresses model. Results show that the residual stresses induced through the producing could be predicted analytically, and the direction of initial deflection remarkably affects the ultimate strength, though clad ratio does not affect so much when it is less than 0.2.
