LS-DYNA MAT_108 Help
(OP)
Hi all,
First off, I am new to LS-DYNA so any suggestions as to where to look for help are greatly appreciated.
Here's my question. I want to use the material MAT_108 (*MAT_ORTHO_ELASTIC_PLASTIC) for a 2D shell model (a heavily loaded precast wall). I put in all the parameters but, I just can't get it to work. LS-DYNA errors out and tells me that the material (which I'm 100% sure I've defined) does not exist. Is there anyone out there that has experience with this material? Is there something I'm missing that a more experienced person would easily know? I've looked at the manuals and I've checked the theory and I can't figure it out. Is there another keyword I need to define? Thanks for your help.

Unfortunately, I pretty sure this is not the problem. I created the Material with a unique ID and I assigned the material to the model using the *Part keyword.
I've also run the entire model using MAT_001-elastic and it runs fine so I'm convinced that the problem lies with the definition of MAT_108. Any other ideas?

Thanks anyway for your help. Anyone else have an idea?

If you want a good Explicit code try ABAQUS/Explicit - it was actually designed rather than evolved and the documentation is excellent.
Good luck.

However, I still stand by my rant regarding the ease of use of LS-DYNA. If you happen to read this post and are planning to make a computer program, just know that there's no such thing as too little documentation.
gwolf, thanks for your help.
