Project

The scaling role of damage inhomogeneity in brittle fracture (IAA200410502)

The project is oriented into the field of physics and micromechanics of failures. For selected inherently brittle materials the damage development at the crack tip during brittle transgranular fracture initiation will be followed. T...
