Abstract The local arc-length method is employed to control the incremental loading procedure for phase-field brittle
fracture modeling. An improved staggered algorithm with energy and damage iterative tolerance convergence
criteria is developed based on the residuals of displacement and phase-field. The improved staggered solution
scheme is implemented in the commercial software ABAQUS with user-defined element subroutines. The layered
system of finite elements is utilized to solve the coupled elastic displacement and phase-field fracture problem. A
one-element benchmark test compared with the analytical solution was conducted to validate the feasibility and
accuracy of the developed method. Our study shows that the result… More >
