Fracture process zone extent and energy dissipation in silicate composites with different cohesive behaviour
Original language description
This paper deals with estimation of the size and shape of the zone of material failure evolving around the crack tip during fracture of silicate-based composites. A technique developed for the task by the authors is briefly sketched and then verified vianumerical simulations utilizing several modelling approaches. The study is performed on numerically simulated responces of three-point bending tests on notched beams of two considerably different sizes made of silicate-based materials with three different compositions resulting in significantly dissimilar cohesive behaviour (from quasi-brittle to quasi-ductile/strain hardening). Numerical simulations by means of physical discretization of continuum (a spring network/lattice-particle type model), fictitious crack model (specialized FEM code), and crack band model (commercial FEM software) are compared with results of the developing technique for estimation of the extent of the fracture process zone (FPZ). The conducted analysis provides
