Project

Nonlinear fracture in structural materials – investigation of expressions of energy dissipation in failure zone via advanced experiments and modelling (GA15-07210S)

During fracture of quasi-brittle/ductile materials the energy dissipates in an extensive nonlinear area at the crack tip. This zone consists of the fracture process process zone. Materials with va...
