Abstract [en]

In the analysis the material is treated as plastic fracturing. A continuum approach to tensile fracturing is related to fracture mechanical concepts. The rate of strain-softening is obtained from the rate of fracture energy being released. Material anisotropy due to the formation of crack-planes is accounted for. The proposed strain-softening tensile fracturing model is implemented in a finite element program for wave propagation analysis. The strain-softening model is compared to an ideal brittle model in analysis of wave propagation in a concrete rod.
