Hello all,
I'm modeling the railways track system, in which the rail wil be affixed to the cross tie by Fastening to against the vertical force.
Now instead of modeling the Fastening, I would like to model the contact between Rail and cross Tie in ABAQUS. I have try surface to surface; surface to node and also tie constrains, but somehow the results are not reasonable (not agree to experiment result). I thinks the problem is contact properties.
So are there any one can helo me on the problem?
PDF position at the University of New Brunswick, Canada
A post-doctoral position is available in the area of material modeling of composite at the University of New Brunswick, Fredericton, Canada. Particularly, expertise is sought in finite element simulation of damage/fracture and thermomechanical properties of fiber composite. Experience in multiscale finite element modeling of fracture and damage behavior of composite materials is required.

Dynamic fracture toughness of PMMA decreases with crack velocity
Dear Alls;
I am loking for the paper which said the Dynamic fracture toughness of PMMA decreases with crack velocity under impact loading, but after crack starts propagation, crack velocity is a decreasing function with crack propagation length.
So, if you know the paper which related to that problem, Could you please show me its title?
Thank you very much,
Best Regards,
Chau
Glass thermal stress and fracture
I have an investigation on glass fracture in fire.
I have a fortran program and it can calculate the thermal stress with steady-state temperature and force load using finite element method, Now I want to change it to transient temperature and force load.
I wonder which method should be taken? I'd like to calculate the fracture at last.
Please help me!
Thank you very much.
ANSYS WB/CFX FSI problem

I am trying to model a tube closed at the two ends by 2 plates. The cavity enclosed by the two plates and the tube is filled with fluid. I fix one end and apply a force to the other end. The tube is a very flixible material and thus all the force should be present as a pressure detected by the fluid.
When I try to do 2-way-FSI in ANSYS WB with CFX, all the force is taken up by the tube and none by the fluid. any suggestions?

mesh refinement for eigen-properties of a cracked body
It is a common technique in modelling cracked bodies with finite element method, to refine the mesh near the crack tip. It is mentioned in text books, mesh refinement is nessecary to increase the acuuracy of the computed stress intensity factor for the crack tip. Is meshrefinement nessecary for computing eigen-properties ( natural frequencies and natural modes ) as well as SIF? or eigen properties are not affected much by the near crack tip field?
