Abstract Being able to seamlessly deal with complex crack patterns like branching, merging and even fragmentation, the phase-field model, amongst several alternatives, is promising in the computational modeling of dynamic fracture in solids. This paper presents an extension of our recently introduced phase-field cohesive zone model for static fracture to dynamic fracture in brittle and quasi-brittle solids. The model performance is tested with several benchmarks for dynamic brittle and cohesive fracture. Good agreement is achieved with existing findings and experimental results; and particularly the results are independent to the discretization resolution and the incorporated length scale parameter. The latter is in contrast to existing phase-field models.
