Micro Abstract:
Understanding the mechanisms of micro-crack initiation in metals is of high academic as well as industrial interest. In this contribution, we discuss the role of stress concentrations in metal matrix composite materials as the cause of crack initiation. Using a continuum representation of dislocation microstructures, we compare microscale simulations to experimental studies of crack initiation and discuss the dislocation microstructure around a crack tip.
