Fracture patterns of quartz particles in glass feldspar matrix

摘要

We report a comparison between experimental evidences and simulation results of the micro cracking in ceramic materials provoked by the cooling process. The solid model and the fracture process are carried out using the Material Point Method. This model, where cracks may initiate and propagate, consists of a quartz particle embedded in a glassy phase. We focus our interest on the key role of the particle morphology on the micro fracture patterns.
