The Stress-Strain State and Potential Crack Trajectories in 2D Elastic Brittle Materials from Steady-State Flow Experiments

A steady-state flow method is used to examine micromechanisms of brittle failure in 2D elastic cracked media submitted to uniaxial compressive stress. The steady-state flow experiments were conducted with an incompressible Newtonian fluid in a Hele Shaw cell. Thin linear rubber inclusions were inserted in the cell to model preexisting cracks and...
