In the automobile, the lightweighting of the body has been required and thus multi-material technology that apply various materials such as steel, Al alloys, Mg alloys and a carbon fiber reinforce plastic (CFRP) to the suitable areas has been progressing [2, 3].
Although the application of light materials such as Al alloys, Mg alloys and CFRP is effective to lightweight the body, from the viewpoint of cost and workability, thin high tensile strength steel sheets have been applied [4, 5].

The partial slip condition affects the residual stresses and shear strain within a thin layer of material near the contact surface [3].
This plasticity model can describe the long term ratcheting behavior and stress relaxation of a material under cyclic rolling contact.
The material constants used in the plasticity model of 1070 steel are given in literature [3].

According to the requirement by the law of similarity on the physical and mechanical performance of model material, the model material should satisfy the following: dam body: density 2,400 kg/m3, elasticity modulus 167, Passion ratio 0.167; dam foundation: density 2,700 kg/m3, elasticity modulus 147, Passion ratio 0.2.
In the calculation model, the material is applied with the completely same material parameter as that in the model test, and only takes the hydrostatic load into account.
Such a method is based on the following causes: 1) There is an error of assuming the concrete as elastic material.
