Benchmarking of Delamination Propagation and Fatigue Growth Prediction Capabilities: Status and Remaining Challenges

In this presentation, the development of the benchmark cases for the assessment of the static delamination propagation as well as the onset and growth prediction capabilities are presented. Examples of automated propagation and growth analyses are shown with a focus on mode II fracture and the simulation of the three-point bending End Notched Flexure (ENF) specimen. Further the selection of the required code specific input parameters are discussed. The current capabilities are summarized while remaining difficulties and future challenges are also highlighted.
