Abstract

In the present work a new mixed mode fracture model for concrete is developed. The model is based on elastoplasticity with damage, and consists of a friction and a cohesion part. The cohe- sion part includes damage, which is capable of exhausting the cohesion as function of the crack opening in an irreversible process. The friction part includes deformation state dependency, which makes the model capable of representing decreasing friction when the crack opens and increasing friction when the crack closes in a reversible way. The performance of the model is compared with results from the litera- ture.
