Quasi-Static Indentation test Analyses of CFRP laminate using quasi three-dimensional XFEM

open access: yesNihon Kikai Gakkai ronbunshu, 2021
CFRP laminates subjected to out-of-plane load may have complex damage such as delamination, matrix crack and fiber failure. In this study, damage propagation analyses for Quasi-Static Indentation (QSI) tests were performed by static implicit method using

Numerical aspects of the XFEM — The XFEM p–Version [PDF]

open access: yesPAMM, 2006
AbstractThe XFEM is known to approximate the displacements and stresses around a crack tip in a very efficient way. But as we will present in this paper we have to deal with a phenomenon coming along with this method that compels us to use higher order shape functions for those elements that are enriched by the crack tip functions.For the computation ...
