Sažetak
The High Fidelity Generalized Method of Cells (HFGMC) has been implemented into Abaqus/Explicit in order to model damage processes in composite materials at the micromechanical level. The HFGMC model is implemented into the finite element code Abaqus via user material subroutine VUMAT. The result of the micromechanical procedure is the computation of strain concentration tensors, which relate the strain tensor on the macro-level to the strain tensor of each subcell. This enables calculation of the stress field within the unit cell, based on the constitutive behavior of each subcell. As the stress distribution is determined for the representative unit cells, calculation of failure criteria and constitutive response of the composite are performed on the micro-level. The most frequently used micromechanical failure criteria have been used in this work as well. Parametric analyses using different unit cell shapes and discretization refinement have been performed. Results of micromechanical analyses confirm significant dependence of failure criteria on unit cell type and refinement.
