Modelling of energy dissipation during fracture of concrete notched beams: Proportion of the effective crack and the fracture process zone consumption

Type

Paper in proceedings (conference paper)

Original Abstract

The paper presents an analysis aiming at capturing the phenomenon of quasi-brittle fracture based on the record of the fracture tests on notched specimens. A method of separation of the energy amounts released for the crack advance and that dissipated within the volume of the sizeable nonlinear zone at the crack tip – the fracture process zone– is introduced. The approach is tested on selected data of published experimental campaigns accompanied with own conducted numerical simulations.
