Prof. Xiaodong Li and I are collaborating in identifying those physical mechanisms that govern the mechanical properties of nanomaterials. Recently, we have a manuscript accepted by the Journal of Applied Physics and would like to share it with you.
Hi guys,
Since I graduated in Germany and I'm looking for a
postdoc position in the States I come across these requested 'letters
of interest' and I really don't quite know how I'm supposed to be exactly composing those.
I'd really appreciate some help. Thanx a LOT!!!
PS I already tried google! ;)
My own DEM(Discrete Element Method) program's solution for static problem seems strange.
I use my program to calculate the displacement of a cantilever under static pressure:
1. it seems my program shows convergence for static problem as the mesh gets denser. As the mesh grows denser(that means the particle becomes smaller), the displacement(of y direction) of the free tip becomes smaller.
Has anyone created a UMAT user subroutine for concrete, capable of cyclic loading. I am interested in modeling a composite steel frame with concrete slab, and the "Damaged Plasticity" model in ABAQUS has convergence issues with the cyclic analyses. If it is possible to get a copy of your UMAT, I am very interested.
Thanks
GS Prinz
I am a third year undergraduate student of IIT Kharagpur (www.iitkgp.ernet.in). In the coming summer, we are supposed to do summer training in some industry in, or out of India, whereas if we want to do internship in a university it must be a foreign university (internship in Indian universities is not allowed).
I am working on pipeline crack detection simualtion using Ansys. since wave propagation is a transient analysis and I have never used Ansys for this kind of simulation. Help me out if you know any source where I can take it as a reference and start my simulation.
Thanks
