Development of Benchmark Examples for Quasi-Static Delamination Propagation and Fatigue Growth Predictions

摘要: The development of benchmark examples for quasi-static delamination propagation and cyclic onset growth prediction is presented demonstrated Abaqus/Standard. example based on a finite element model Double-Cantilever Beam specimen. independent the analysis software used allows assessment automated propagation, capabilities in commercial codes virtual crack closure technique (VCCT). First, was created Second, static results, were created. Third, load-displacement relationship from results compared, good agreement could be achieved by selecting appropriate input parameters. Fourth, starting an initially straight front, allowed to grow under loading. number cycles during each increment obtained compared examples. Again, between benchmarking procedure proved valuable highlighting issues associated with choosing parameters particular implementation. Selecting parameters, however, not straightforward often required iterative procedure. Overall are encouraging, but further mixed-mode required.
