Abstract: The deformation of natural clays is induced due to the damage of structure. The total deformation consists of 3 parts, i.e. elastic deformation of structure body, plastic deformation due to sliding in the structure plane and irrecoverable deformation due to crushing of structure body. The sliding yield surface is considered as isotropic hardening and rotating hardening bounding surface. The plastic modulus is interpolated by using the 'real stress' and 'image stress' on the bounding surface. It is stipulated that damage deformation occurs under loading or inverse loading conditions rather than under unloading condition. The bounding surface masonry model is developed and verified by using test data.
