Damage-cluster distributions and size effect on strength in compressive failure [PDF]

, 2012
We investigate compressive failure of heterogeneous materials on the basis of a continuous progressive damage model. The model explicitely accounts for tensile and shear local damage and reproduces the main features of compressive failure of brittle ...
