Hi Bartosz, Thank you very much for your post. That was great help! Many thanks! Fabian

thread799-269244 Hi there, I am currently working on a VUMAT for a material degradation law. To obtain better results, I want to bypass the characteristic length from Abaqus and want to get the element coordinates. I managed to get the nodal coordinates into my routine. however, for this I...

Thank you for your reply! I had a look in the output files again and it seems that in my altered models the shell doesn't deform at all while before a clear deformation was visible. I tried to compare the input files, but for me it just looks like I changed the mesh and the dimensions of the...

Hi everyone, I have the following problem: I have modelled a plate with continuum shell elements and impact it with an rigid body. My first modells were quite alright with the plate deforming and the impactor bouncing back. Now i somehow changed something (I don't know what) and the plate seems...

Hi everyone, Since a couple of days I try to model (Abaqus 6.8 Explicit) an impact on a composite plate which includes a cohesive layer for delamination. Since I use a VUMAT for shell elements, I want the layers be modelled in conventionell shell elements. However, I could not get it working...

Is there a way to apply a density and a stiffness to the rigid part? Many thanks for your help Fabian

Dear All, I have a Impact/Contact problem too. I impact a composite shell plate with an analytical rigid impactor. but instead of a smooth acceleration during impact, the graph shows an edgy oscillating curve. I use the general contact...
