Dear everyone
My project is about the adhesional friction between rubber and a rigid surface. In this case I have modeled a block of rubber which is sliding on a real rough rigid surface in ABAQUS.
Hi everyone,
I am working on the Finite Element Analysis of a metal forming process. I have created the rollers and the mandrel and the roller as analytically rigid surface and the blank as 3D deformable solid.
Hey all
As a part of my effort to learn how to use Abaqus, i was trying to simulate a familiar contact problem which i found in the internet.
fortunately, the document with the descripition of the problem included detailed guidance as to how to create the model.
after i have followed the precised phases needed, i completed the model and it ran OK. the results showed the same patterns of contact and general behavior but the stresses were 2 times greater.
i have no clue what the problem could be because i followed the steps precisely.

12th to 15th August, 2013 in Shanghai. The Sixth International Conference on
Nonlinear Mechanics is dedicated to the latest advancements in the science,
technology and applications of nonlinear mechanics. The conference will provide
a forum for academic researchers, engineers, and students to summarize the
Hello,
I'm modelling an impact of a rigid body with a deformable plate (shell elements) in the dynamic explicit analysis. When defining contact parameters, I can add the damping coefficient. I'd like to know what value is typical for this parameter? After some computations, I've found that 0,01...0,05 was rather good for my model. Is that a reasonable value?
Thanks
Hi,
The problem I want to solve is: instabilities that arise due to
molecular potential (VDW interactions) when a rigid solid block
(contactor) approaches an elastic film bonded to a support (no
interactions or slip whatsoever between the film and the support). These
interactions come into play when the air gap between the elastic film
and contactor becomes less than some critical distance. I want to do
this in Abaqus Explicit.
a) I have tried using cohesive zone model traction-separation law (on
Hi..
My model consisits of two steel plates. Top plate has curved bottom and bottom plate is rectangular. Top plate is resting over the bottom plate. There are 3 steel pintels between the bottom face of top plate and top face of bottom plate to prevent running of top plate. Sliding is allowed between the contact surface of top and bottom plate. Pintels are fixed to the grooves made in the bottom face of top plate and frictionless hard contact is defined there.
Loading - Vertical pressure of 5MPa on top face
Two recent publications in International Journal of Solids and Structures regarding the Analysis of Knoop Indentation.
Maybe they are of some interest to contact mechanicians.
hi all,
I have some problems with contact elements in ANSYS.
My model is a cube of matrx containing two fibres with periodic boundary conditions. The interface between Matrix and Fibre is modeled with contact elements and cohesive zone law.
In 2-D everything works out just fine when bringing up displacement in x-direction. Here is a movie I made of the Contact Status over the loadsteps:
