摘　　要：Hyperelastic model with damage induced compressibility is implemented in the ABAQUS software using the subrou- tine Umat. A thermodynamic model is proposed taking into account the nonlinearity of the material behavior. Within the present work, the behavior of laminated rubber bearing structure is studied for two geometrical sets of materials (A-type and equivalent material) under complex monotonic loading conditions. A new geometric edge of laminated rubber bearing is proposed in order to reduce the development costs of the structure. The proposed model allowed finding a good homogenized damage distribution for the same overall stiffness.Hyperelastic model with damage induced compressibility is implemented in the ABAQUS software using the subrou- tine Umat.
