Micro Abstract:
In this contribution, the numerical simulation of brittle fracture of glass materials under room temperature is carried out on a continuum-mechanical scale using the theory of linear elasticity and J-integral, extended by a phase-field modeling (PFM) approach. Following this, behaviors such as crack nucleation, propagation, and bulk material fracture can be realized. Moreover, fracture stresses and J-integral values are compared to analyze material toughness.
