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...
Alright, thank you for your answer. I had already tried to extract the reaction force from the target boundary, but the results were inconsistent (maybe I did it incorrectly). However it works fine with the contact force, thanks!
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...
Alright, thanks for checking. I have a symmetric boundary condition on the node set of interest. Maybe that's the culprit.
In my case, print(len(myNodeSet.nodes)) gives the good number of nodes, but getSubset(region=myNodeset) returns whatever.
Surprisingly enough, my workaround involves using...
I wondered the same thing, since I use 8-nodes elements, and I have exactly 8*130 = 1040 values. However, the node labels make no sense at all. They do not correspond to nodes I defined, they repeat, and they feature extremely low force values.
In any case, I have a workaround and I can still...
In essence, that's already what I do. I just count the number of entries in rmyNoddeSetValues instead of printing them. I just ran your code, and I get 1040 printouts, with inconsistent node numbers. Below are the first and last 5 printouts:
22 [-13.433395 -0.46440947 -0.02727298]
23...
Thanks NRP99. The statement: myNodeSet = odb.rootAssembly.instances["TENSILE"].nodeSets["SYMX"] already creates an OdbSet, containing the 130 nodes of my set. I still do not know why, when I later use getSubset(region=myNodeSet), I end up with more than 130 nodal values. Worse even, these values...
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...
Alright, after multiple trials, I have the solution: I removed the *Restart, write card from the first job and all came together. As restart files are automatically written by ABAQUS Explicit, it feels like using a *Restart, write explicitly in the first job makes for a double usage??
The weird...
Thanks for the advice, I'll try something like that also. I just noticed that my .res file is only 260 Ko big, and that the results of step 1 are not transported to the new job. I suspect Abaqus does not save the restart information correctly, hence the error. I'll try to fix that first.
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...
As FEA Way mentioned, the couple of keywords *DAMAGE INITIATION and *DAMAGE EVOLUTION are used to define progressive damage. Subsequently, it is adapted to ductile materials. In your first example, I would still refer to the first drop as the onset of damage. However, given that you have a...
I thought I tried that too already (even before my first post). I'll try again, for good measure, but I am already satisfied with the "no automatic free surface generation" answer. Thanks anyway!
Alright, thank you both for your answers.
@Mustaine3: I was precisely wondering if I could do without editing keywords. I already set up my simulations using input files, but I wanted to share a CAE-only version. However you confirmed to me that there was no automatic recognition of interior...
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
