Abstract
The phase-field approach to fracture became quite popular in the recent years. Despite its advantages such as the possibility to use a standard finite element formulation and a standard meshing technique, it has drawbacks regarding the numerical implementation. Reasons for that are i.a. the bi--convexity and the non--smoothness of the problem. The goal is to develop an efficient algorithm that can be applied to multi--field phase--field fracture problems. The benchmark and development of this algorithm is done based on a brittle fracture model. Furthermore the model for phase-field fracture is extended to poro-elastic-plastic solids capable of simulating hydraulically induced fractures in a porous medium undergoing elastic-plastic deformations.
