GPFniCS: A generalised phase field method to model fracture

Advanced damage tolerance design of materials and mechanical components heavily relies on fracture failure analysis. A robust, efficient, and versatile software (GPFniCS) is developed and provided for public access to perform fracture analyses based on the Generalised Phase-Field Method. GPFniCS software is developed on top of FEniCS, an open-source finite element library. One-dimensional and two-dimensional mixed mode problems are validated with GPFniCS and provided as illustrative examples in a public repository. The software shows excellent potential for computational fracture studies, and it is open to further developments in various fields like thermal loading, fatigue loading, solidification, and many more.
