Experimental and numerical study of glass fracture using J‐integral and phase‐field modelling approaches

Experimental and numerical study of glass fracture using J‐integral and phase‐field modelling... In this contribution, an experimental study and FE simulations based on J‐integral theory and the phase‐field modelling approaches are presented in order to systematically study the temperature and strain‐rate dependency of glass fracture behaviour. First, a series of three‐point bending tests are successfully carried out under different stain‐rates and temperatures. Secondly, numerical modelling of the bending tests with the introduction of a micro crack yields the stress‐strain response, which serves to the calculation of J‐integral values, in order to describe the glass fracture resistance in terms of energy.

Abstract

In this contribution, an experimental study and FE simulations based on J‐integral theory and the phase‐field modelling approaches are presented in order to systematically study the temperature and strain‐rate dependency of glass fracture behaviour. First, a series of three‐point bending tests are successfully carried out under different stain‐rates and temperatures. Secondly, numerical modelling of the bending tests with the introduction of a micro crack yields the stress‐strain response, which serves to the calculation of J‐integral values, in order to describe the glass fracture resistance in terms of energy. At the end, the critical energy release rate serves as a bridge connecting the J‐integral theory with the phase‐field modelling, where a dynamic fracture model with crack propagation is realised as a new direction for further researches.
