Translation rule of elastic-core in subloading surface model

抄録

The translation of the elastic-core, i.e., the similarity-center of the normal-yield and the subloading surfaces is incorporated in the extended subloading surface model. The rigorous translation rule of the elastic-core is formulated in this article. It is derived based on the mathematical proof due to the enclosing condition inside the limit elastic-core surface. It is applicable to the general deformation behavior including the softening behavior observed often in soils.
