摘要: ABSTRACTWith the increasing implementation into commercial finite element (FE) codes ofcapabilities for simulating delamination growth in composite materials, need forbenchmarking and assessing these capabilities is critical. In this study, benchmark analyseswere performed to assess propagation simulation of VCCTimplementations Marc"m 2008r1 MD Nastran"m R3 v2008.0 solution sequencesSOL 400 SOL 600. Benchmark results Double CantileverBeam (DCB), Single Leg Bending (SLB) End Notched Flexure (ENF) specimens weregenerated using a numerical approach. This approach was developed previously,and involves comparing from series analyses at different lengths toa single analysis with automatic crack propagation. Experimental analytical benchmarkdelamination were also taken literature second DCB specimen.Specimens analyzed three-dimensional two-dimensional models, andcompared previous Abaqus ¨ VCCT implemented. The resultsdemonstrated that capable ofaccurately replicating results. Marc
