Damage modeling using higher-order finite element formulation

In the presented research, the two dimensional C1 continuity triangular finite element is used for the modeling of the quasi-brittle softening phenomena. The implemented damage model is based on an isotropic damage law applied upon the higher-order stress-strain constitutive relations originating from the full strain gradient theory. Both homogeneous and heterogeneous materials are analyzed, where the material stiffness behavior is introduced in the computational model through the constitutive tensors obtained using the second-order homogenization procedure. Parametric analysis of the model is performed by changing the values of an internal length scale parameter. All the algorithms derived are implemented into the FE software ABAQUS via user subroutines. The verification of the presented computational model is performed on the benchmark example.
