A unified framework for an impromptu switching between the coupled (i.e., the monolithic), the staggered, and the uncoupled solution strategies for the phase-field based computations of material fracture is presented. As a model problem, a 2d quasi-brittle solid phase-field formulation, which is based on the tension-compression split energy functional, is chosen. In order to fit within the proposed framework, the classical staggered approach is reformulated as a loop of uncoupled monolithic steps that we call modified-staggered. Numerical examples show that an automatic switching between the coupled and the modified-staggered solution methods (when the former fails) may shorten the computational times (compared to the pure staggered approach) for an order of magnitude.
