    XY data report : Contact output duplicated

    Hello, I am studying contact between two solids in a plane stress formulation. When I want to output the contact information at one of the contact surfaces (lines in 2D), i first defined a Path that is one of the contact surfaces, than made XY report. I got duplicated nodes like :" /...

    Viscoelastic Material properties PMMA

    Dear all, The structure I would like to model is made of PMMA: E = 3.2 GPa, nu = 0.4. More parameters are in the uploaded image: https://files.engineering.com/getfile.aspx?folder=e8616049-c9c4-46aa-9ad7-6415bbebc950&file=PMMA.png When modelled as linear elastic, the obtained results are...

    Discontinuous stick slip open zones

    Exponential decay or test data are the same. In the second option, you do not specify dc, that's it.

    I have tried also Node to surface contact and obtained similar results.

    Discontinuous stick slip open zones

    Of course the pressure and gravity are both propagated until the end of the analysis. For the application I have used all of the available possibilities: Quasi-static, moderate dissipation, transient fidelity. I have even tried with entering alpha, beta and gamma myself to have different...

    Discontinuous stick slip open zones

    Hi Everyone, I am trying to reproduce the experimental results of a friction rig. I have two plates (modelled here as 3d solids) one above the other. After applying a normal (vertical) pressure (step 1) I start pushing the plate one at the top until the first sliding occurs (step2). Then in...

    mesh origin in abaqus

    Hi all, I have built a model using cae and put the frame origin at a corner for parts and mesh like in the attached mesh figure. When I generate an inp file, I saw nodes with coordinates that does not correspond to what I expect: I have negative Y coordinates while all the mesh should be above...

    Contact Friction Coeff

    Thank you for your reply, but before asking I have checked all the documentation and could not find the answer. I have read section 37.1.5 of the user analysis guide. regards
