Hello,
I am trying to implement the time integration scheme proposed by Combescure et. al [1] to simulate a dynamic crack propagation problem in XFEM (2D edge crack under impact loading). But I have an interesting question to ask.
I have been looking at XFEM literature for a while and wondering why do we need 2 different heaviside enrichment functions in XFEM? In paper titled "A finite element method for crack growth without remeshing" by Nicolas Moes et al.(1999), they use the following function for heaviside enrichment:
H(x,y)={1, for y>0
-1,for y<0}
Hello everyone,
I was looking for a Matlab source code for implementing XFEM to solve a dynamic problem (specifically dynamic crack propagation problem). I found several source codes which only solve static problems (they don't calculate mass matrix and they don't do the time integration).
My research goal is to remove the oscillations from stress intensity factors for a dynmic crack propagation problem. I will really appreciate any kind of help/suggestions.
With respectfully
Bhuiyan, A B M Abdul Ali
Dear all,
As part of the USACM's 13th U.S. National Congress on Computational Mechanics (USNCCM13) to be held in San Diego, California, July 26-30, 2015, we are organizing a minisymposium on
advances and applications in Generalized/Extended Finite Element Methods.
