Development of a Benchmark Example for Delamination Fatigue Growth Prediction

摘要: The development of a benchmark example for cyclic delamination growth prediction is presented and demonstrated commercial code. based on finite element model Double Cantilever Beam (DCB) specimen, which independent the analysis software used allows assessment capabilities in codes. First, result was created specimen. Second, starting from an initially straight front, allowed to grow under loading number cycles onset during stable each increment were obtained analysis. In general, good agreement between results could be achieved by selecting appropriate input parameters. Overall, are encouraging but further mixed-mode required.
