abaqus implementation of xfem
hello,everyone!
I'm a freshman on abaqus implementation of xfem.Can anyone send me some simple example to me for learning?I have learnt some papers written by pro.Giner,but I really cant understand the heaviside function. That is why I come here to ask someone for help.
best wish!

Subspace Iteration eigenvalues and eigenvectors--efficient implementation?
Choose a channel featured in the header of iMechanica
Anyone knows an efficient implementation of the subspace iteration method to compute a few lower eigenvalues and eigenvectors of a generalized problem KG*u=lambda*KS*u or any similar method? i.e., to compute the buckling loads and modes.
I'd like to use something optimized to Intel or amd64 processors or similar, like MKL, etc.
This is for bifurcation buckling analysis. KG is the stiffness matrix. KS is the geometric stress matrix. Both constructed from a FEM discretization.

Does any body know the height of center of the gravity of the bugatti veyron?
Strengthening alginate/polyacrylamide hydrogels using various multivalent cations
We successfully synthesized a family of alginate/polyacrylamide hydrogels using various multivalent cations. These hydrogels exhibit exceptional mechanical properties. In particular, we found that the hydrogels cross-linked by trivalent cations are much stronger than those cross-linked by divalent cations. We demonstrate stretchability and toughness of the hydrogels by inflating a hydrogel sheet
Running MD simulations with LAMMPS
In appendix A of my PhD thesis, I share a MATLAB code to get coordinates of carbon atoms in a graphene sheet. The code also generates the data file required for LAMMPS. In addition, I included a sample input and the corresponding output files from LAMMPS. I hope this will be useful for those who would like to learn MD simulations.
Visual Molecular Dynamics (VMD) package can also be used to obtain coordinates of graphene.
Determination of Density of Laminated Composite
Dear Engineers,
I would like to determine the density of laminated composite which consists of one lamina E-Glass/Epoxy and another one is thin layer of steel plate due to determining Young's Modulus through non-diestructive technique-Impulse excitation.
Any suggestions would be welcome.
