2041 Three-Dimensional Crack Analysis using Virtual Crack Closure-integral Method (VCCM) for Quadratic Tetrahedral Finite Element
Details
A three-dimensional virtual crack closure-integral method (VCCM for quadratic tetrahedral finite element to evaluate the energy release rate and the stress intensity factor is being developed. Use of tetrahedral finite elements has became a sort of standard way in the analyses of three-dimensional complex structure/solid structure, due to the recent advancement of automatic mesh generation software for tetrahedral elements. In this paper, procedures to evaluate the fracture parameters and some numerical results are presented.
