Fracture in structures is usually to be avoided or, if intended like for airbags or peel foils, it should occur along a predefined crack path. The integrity and usability of a part has to be ensured over the lifetime of the structure. In order to optimize a structure at the design stage, simulations allow to analyze and to predict the structural behavior for a development of the best layout. The contribution at hand presents appropriated material modeling strategies for polymers and introduces the so-called configurational force approach for inelasticity and finite strains as a method to analyze the energy release rate, the crack advancement and the crack growth direction. Certain numerical methods like cohesive elements, containing e.g. inelastic cohesive zone models and the node splitting approach combined with an r-adaptive discretization are shown as valuable simulation features.
