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 calculated with the developed method does
not depend on the selected size of loading increments. The results of several numerical experiments show that the
improved staggered algorithm is efficient for solving the more complex brittle fracture problems.},
