A phenomenological approach based on the empirical formulation of stresses and strains is followed in this paper, utilising the theory of viscoplasticity in the general framework of the finite element method for modelling the progressive fracturing of softening materials in transient dynamic problems. The central difference method is used for a step-by-step direct time integration of equations of motion, which is coupled with lumped mass and proportional damping matrices. In the context of the rotating smeared crack approach, it is assumed that micro-cracking is initiated upon the violation of a yield criterion and is further governed by the strain softening process. The progressive damage is assumed to be isotropic and is modelled with the gradual reduction of the load carrying capability. The occurrence of strain softening in the continuum leads to the localisation of deformation, which causes a local failure through the occurrence of cracks in the localised zones.
