Description

In this model, the residual strength criteria is introduced, and the Mohr-Coulomb's failure criterion is expansively appllied to the modelling of the strain softening under compression. The cohesion and the friction coefficient are assumed as functions of tangential component of sliding displacement in the shear band. The strain softening response is described in connection with the sliding mechanism. The functions of the cohesion and the friction coefficient are evaluated based on the stress-strain relationships obtained from experimental data which are carried by authors.
