We address the simulation of dynamic crack propagation in brittle materials using a regularized phasefield description, which can also be interpreted as a damage-gradient model. Benefiting from a variational framework, the dynamic evolution of the mechanical fields are obtained as a succession of energy minimizations. We investigate the capacity of such a simple model to reproduce specific expe...

Asphalt mixture is a type of textured composite material made aggregates and mastic part. Overall strength failure behavior in such materials depends on the texture or heterogeneity mixture. In particular, crack growth mechanism from tip pre-crack significantly affected by asphalt environmental conditions. The can extend through soft mastic, tight interface mastic/aggregates. this research, per...
