Numerical Investigation of the Stress-Strain State in the Vicinity of Holes System and Shear Cracks

The article studies stress-strain state of elastic-plastic material nearby the system of holes and shear cracks. The elastic-plastic behavior of the material outside the cuts is described using the yield function and the flow potential. This allows us to take into consideration the internal friction and the dilatancy. The finite elements method is used for numerical modeling.

Key words: shear crack, elastic-plastic material, stress-strain state, hole.
