Abaqus/Explicit

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?

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 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.

This Technology Brief describes Abaqus/Explicit
modeling of the ballistic impact of metal projectiles on metal targets.
It will demonstrate the utility of Abaqus/Explicit as a tool for
reducing the amount of experimental testing as well as assessing the
projectile residual velocities and time-resolved kinematics. 

Hi all,

 I am new in the Forum, and I am looking for some informations regarding how to simulate nonlinear material in explicit.

I am tryng to analyse the behaviour of a roller rolling on the sand (or mud), but the results I get with a basic elasto-plastic material are not very accurate, expecially because I cannot set the tension allowed in the sand to be zero.

Other ways to input nonlinearity in Explicit are always refused by ABAQUS. Is there any way to get something more accurate?

Hi,
Here is the issue:
I am working with a x64 version of
Abaqus/Explicit (6.8-2), and a 32bits version (6.7-1). MS VS2005 is
installed with the x64 compiler tools, Intel Fortran is correctly
installed (IA-32 and Intel64 versions). My OS is Windows Vista Enterprise (64 bits).
The routine is compiled and linked correctly by lauching the appropriate ifortvars.bat file prior to executing abaqus.

Everything works perfectly with the 32 bits version of Abaqus+Compiler, with one or more processors (I have 8 of them).
