Cracks and destruction of glass occur, so it can be said that it is important to consider methods for evaluating the features and safety of glass. Although the features and safety of the glass have been experimentally evaluated, quantitative evaluation by numerical analysis is also necessary. Peridynamics is attracting attention as to the breakdown phenomenon of glass. This method is an analytical method that expresses a continuum by a particle model, and reproduction and analysis of destruction phenomena are expected. In this paper, we simulate DCDC method which is experimental method to investigate the mechanical properties of glass by Peridynamics. By comparing the analytical results on crack growth with experiments, we will examine the usefulness of Peridynamics in numerical analysis of glass. Solver uses Peridigm, an open source software using Peridynamics, to reproduce the DCDC method with a 2D and 3D model of Ordinary state-based PD (ODSBPD) and Non-Ordinary state-based PD (NODSBPD), which makes it easy to reproduce cracks. Analysis by changing the loading pressure showed the same tendency as in the experiment that the crack length became larger as the pressure became larger and crack propagation stopped when the energy was in equilibrium state. Therefore, it was found that the DCDC method can be reproduced by Peridynamics.
