    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 :" /...

    *EL print

    Hi ll, I wanted to get the stresses at an ELSET and wrote: *EL print ,elset=ELsetFront_HB,POSITION=AVERAGED AT NODES,frequency=100000 S11, S22, S12 I got a table like : NODE FOOT- S11 S22 S12 NOTE 1 -4614. 1.2010E+06 5178. 5 -5.7100E+04 1.6403E+06...

    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

    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...

    Discontinuous CSLIP from step to step

    Hello, I am making contact friction analysis with abaqus. In a first step, I load my structure like this: *Step, name=Step-2, nlgeom=yes, inc=100000,UNSYMM=YES *Dynamic,ALPHA=-0.0,GAMMA=0.5,BETA=0.25 0.1,89.41,2e-10,0.50 *************** *Controls, ANALYSIS=DISCONTINUOUS *CONTACT CONTROLS...

    Abaqus Explicit parallelization

    Dear all, I have usually run abaqus standard in parallel with the classical cpus = option. Today, I am trying to do the same for an explicit computation. I run with: abaqus job=myjob cpus=2 and I got : mpirun: Warning one or more remote shell commands exited with non-zero status, which may...

    Contact Friction Coeff

    Dear all, I am using abaqus for modeling a friction problem between two deformable bodies. My question is that I am using and exponential decay friction law, means that the fric coeff depends on the slip rate. *Friction, slip tolerance=0.001, exponential decay 0.9 0.12, 3.0e-9 0.1 I made some...
