Hi,
I have written a VUMAT for Johnson Cook Model. I would like to use subroutine VUEOS to define linear Mie-Gruneisen equation of state. The USUP type VUEOS subroutine can be found at Abaqus Documentation.
However, I am not able to figure out how to combine the two subroutines. What needs to be called from VUEOS into VUMAT?
Hello everyone!
My goal is to model large plastic deformations of polycrystalline metals using crystal plasticity and ALE adaptive meshing. In order to do that I want to use VUMAT subroutine in Abaqus/Explicit, since as far as I understand Abaqus/Standard is not good for large deformations and it doesn't support ALE adaptive meshing for that purpose.
Hi everyone;
I'm trying to simulate FSW plunge state using Abaqus/Explicit, Coupled Eulerian-Lagrangian technique.
As you can see in the picture, NT11, PEV and EVF are calculated. But the problem is that the elements in base metal are not deformed. In other words, the base metal elements which are in contact with PIN remained intact and are not deformed.
Anyone could help me with this?
Hello everyone,
I made simple cantilever model in Abaqus/Explicit. For concrete I have used Concrete damaged plasticity model and for reinforcement I have tried two models (one with Truss and second with Beam elements). I have assigned displacement as BC (Smooth amplitude) in Reference Point at the end of the beam, and I have coupled RP with the end of the beam. For concrete beam I have used C3D8R elements.
For history output I have requested Reaction force in RP and energies for whole model.
But results I am getting aren't expected.
Hello all,
I'm trying to model composite delamination under non-severe impact on layered composites in ABAQUS/Explicit.
To begin with, I've modeled a 2D aluminum with a finite very low thickness cohesive layer with traction-separation behavior between. Then, I give some displacement to the middle-top node to simulate an impact scenario. However, even in this simple configuration, I'm having stress distribution problems when the models with cohesive layer between and without cohesive layer are compared.
Hi Guys,
I'm having trouble in creating a sudden decelleration of a body using Abaqus. Similar to a shock but no actuall impact. I whant to measure the body response for stress and strain along time.
Does anyone have a good tutorial that I could use as a guide?
I would appreciate your reply.
Cheers
Hello everyone,
I need some help regarding the definition of initial residual stresses and plastic strains in a shell finite element (S4R) model in ABAQUS/Explicit.
I have determined the residual stress distributions and initial plastic strains and I need to assign these distributions to a given element set.
I understand I should be looking at:
*INITIAL CONDITIONS, TYPE=STRESS
ELSET_A, S11, S22, S33

Hi, I am working on modeling wave propagation in ABAQUS/CAE.
I am not expert on ABAQUS and trying to figure out how it works.
I have a 2D Shell steel plate (1 centimeter by 1 centimeter) and try to obtain wave speed at any points of plate.
I put the material properties in and used ABAQUS/Explicit analysis.
Time steps are 1E-009 seconds and there are 2 steps (impulsed at the first step and propagates at the second step).
The load pluged at the amplitude with equaily spaced for 0.1 micro seconds (so it becomes impulse load).
