    Corotational coordinate system in a VUMAT

    Hi, As I understand from the VUMAT documentation, the coordinates of tensorial quantities in a VUMAT are expressed in a corotational coordinate system. The later is either the global coordinate system, or a user-defined orientation, rotated by R, where R is obtained from the polar decomposition...

    Reaction force on rigid body

    Hi, I am modelling a rigid projectile impacting a target in abaqus explicit 2021. The projectile has a reference point, with a mass and an initial velocity along the y direction. All other DOFs are constrained on the projectile. The simulations run well, but I cannot figure out how to extract...

    ABAQUS scripting region argument yields inconsistent nodeSet

    Hi all, I have a simulation of a tensile test featuring 10010 nodes, and in that simulation I have a node set of 130 nodes named "XSYM", for which I would like to extract nodal forces using python scripting. I run the following code, which is pretty standard, but the call to getSubset creates...

    Restart analysis with *Extreme element value

    Hi all, I am trying to simulate a classical tensile test on a sheet specimen in abaqus explicit, but I want to stop the simulation after PEEQ exceeds a given value (say 0.1). I use the statements: *Step, name=Step-1 *Dynamic, explicit ,100 [... bulk viscosity, mass scaling, boundary...

    Eroding projectile impacting eroding plate in CAE

    Hi all, I guess the question is in the title: is there a way to model the "Eroding projectile impacting eroding plate" problem in the CAE? Especially, can the elemental eroding surfaces be created in the CAE? Thanks
