Variational phase-field models of brittle fracture are powerful tools for studying Griffith-type crack propagation in complex scenarios. However, as approximations of Griffith's theory-which does not incorporate a strength criterion-these …

Phase-field models of fatigue are capable of reproducing the main phenomenology of fatigue behavior. However, phase-field computations in the high-cycle fatigue regime are prohibitively expensive due to the need to resolve spatially the sm…

In the context of the Damage Mechanics Challenge, we adopt a phase-field model of brittle fracture to blindly predict the behavior up to failure of a notched three-point-bending specimen loaded under mixed-mode conditions. The beam is addi…

Phase‐field modeling of brittle fracture along the thickness direction of plates and shells Open
The prediction of fracture in thin‐walled structures is decisive for a wide range of applications. Modeling methods such as the phase‐field method usually consider cracks to be constant over the thickness which, especially in load cases in…
