Simulations of Shear Zones and Cracks in Engineering Materials Using eXtended Finite Element Method

Numerical simulations of cracks and shear zones in quasi-brittle materials are presented. Extended Finite Element Method is used to describe both cracks and shear zones. In a description of tensile cracks, a Rankine criterion is assumed. A discrete Mohr-Coulomb law is adopted for simulations of shear zones. Results of simple numerical tests: uniaxial tension, bending and biaxial compression are demonstrated.

Scientific work has been carried out as a part of the Project: “Innovative resources and effective methods of safety improvement and durability of buildings and transport infrastructure in the sustainable development” financed by the European Union (POIG.01.01.02-10-106/09-01). The FE-calculations were performed at the Academic Computer Centre in Gdansk TASK.
