The phase field approach to fracture has attracted much attention since its first applica- tion to brittle fracture in 1998, due to its unique simulation potential and easy implementation. The present work aims at reviewing the most recent advances to render it a high-fidelity computational method able to quantitatively solve problems of high engineering relevance. Specifically, the follow- ing major issues are addressed: (i) quantitative validation of the phase field models in relation to experimental tests involving complex crack patterns; (ii) extension of the basic formulation within a multi-phase field framework to simulate damage in compression and crushing failure in addition to tensile cracking; (iii) interplay between bulk fracture and cohesive interface delamination in compos- ites, for statics and dynamics. Conclusions highlight perspective research directions.
