Hi
I amtrying to model a simple compression test om a foam cube with LS DYNA. I have tried a lot of different approaches but there is always something wrong in the model :(. I have managed to get on model up and running, but i am having problems with excessive penetrations! Do anyone have any idea how to fix this?
I have includef the .k file as a text file to this post.
How do i add a reinforcement beam to a door of a car at the front using the ls dyna contact card CONSTRAINED_RIGID_BODY ?

Hi I am working on the designing of a crash test bench to measure vehicle door intrusions ?
Could some one provide me basic ideas on the test bench set up and how to mout the door on the test rig and which degrees of freedom to lock ?.

I'm using elastic solid elements to model wave propagation in an
structure in LS-DYNA. I need to add the effect of dissipation in the
system by using viscoelastic material model (MAT_006). All I know from
my material is storage & loss modulus (E=E'+E"*i). I was wondering
how can I transform these parameters into G0, GI and BETA needed by
MAT_006 (G=Gi+(G0-Gi)*exp(-beta*t))?
Dear all,
I'm using LS-Dyna and I would like to model the interaction between a viscous fluid and metallic substrates.
If everything is working in 3D, it's not the same with the 2D...
Indeed I've used each contact algorithm (I think) in LS-Dyna and each time the contact between my 2D elements and the sph is not initiated.
Does anyone has an explanation to this curious problem ?
Maybe I'm not using the good contact setting.
Or contact between sph and 2D elements is not available in LS-Dyna.
Dear all,
I'm writting an usermat into a vectorized subroutine in LS DYNA. The implementation is a non-local model based on an avarage of the strains.
For the implementation I need to know the strains for all the elements at each iteration to compute the non-local strains of all the elements.
Hi all,
I am trying to replicate an analysis done in Abaqus by using LS Dyna. I've an input(inp) file of the abaqus model on which the analysis has been performed.
