Is there a material model in LS-Dyna which can deal with plastic tangent moduli higher than the elastic young´s modulus?
An increase in material stiffness results in negative plastic true strains. Using it as input for MAT_24, negative plastic true strains are ignored and set to zero.
Can you...
Hey there,
I´d like to simulate a composite material with matrix and fibres in a prestressed condition (due to different CTE). Therefore I have to take into account that the material´s response due to the stressed condition changes with the amount of prestress.
In Ansys there´s the command...
Hey there,
I m looking for a way to simulate a material in LS-DYNA with two different youngs-moduli (one for tension, one for compression). Furthermore it should have two different yield points (one for tension, one for compression). Please see also the image attached...
Hey guys (and girls :),
i d like to simulate thermal stresses in a hybrid material consisting of several different materials. Static Analysis is all fine and yields nice results.
Now for a thermal analysis i d like do some research on the thermal expansion and on the resulting stresses.
To...
Hi,
I have a simulation model consisting of several layers which are divided into sections. In the odb.-file, I´d like to
chose some of the sections and save them into a new odb-file.
My problem is, that a fieldOutput that I implemented has values for the layers that are too different to...
Hey there,
I´m researching composite structures with Abaqus and
I`ve written a script to evaluate failure criteria - i.e.
efforts of the structure. This is done by accessing the
odb-file and writing a new FieldOutput to it (Hashin- and Puck-Criterion).
So far everything worked well. But...
