...P. Raghu; A. Rajagopal; J. N. Reddy In this work, we propose a thermodynamically consistent phase-field model for the brittle fracture analysis of thick plates. A hybrid model, which is fast and accurate, is proposed for the phase-field modeling of fracture in thick plates. Reddy’s third-order...
