APPLICABILITY OF MODIFIED VON-MISES DAMAGE MODEL TO COMPRESSIVE FRACTURE BEHAVIOR OF CEMENT-BASED MATERIALS

Abstract

The Applicability of the damage model based on the modified von-Mises criterion is studied for compressive fracture behavior of cement-based materials. First, crack propagation behavior of mortar plate with a circular hole subjected to compressive loading is simulated using the finite element method with the modified von-Mises criterion, and the results are compared to the existing experimental results. To verify the capability for simulating the compressive fracture behavior quantitatively, the numerical results are compared with our own test results. Finally, finite element models with different mesh size are used for investigating the influence of mesh size on the numerical results of compressive fracture behavior.
