Hi missil3, I did some calculations. The strain ouput by ELOUT via ASCII is engineering strain. I calculated the engineering strain based on the node displacement and the calculated strain fits perfect to the curve plotted by ELOUT. For the strainrate output LS-DYNA calculates the true strain...

Hi, are the stresses output by LS-DYNA for example via a fringe plot or a graph by ASCII Element output engineering stresses or true stresses? The stresses are always described as "effective stress" but I'm not sure wether they are engineeringe stress or true stress Many thanks in advance...

Hi missil3, works!!! Thanks! Best regards, Leibi

Hello, I've got a question concerning the input commandos in LS-DYNA. I'd like to use the secound damage model beneath GISSMO in *MAT_ADD_EROSION. Unfortunately I'm not able to enter the right menu because I can't enter the right value concerning the parameter IDAM. What is the difference...

If you have created the volumes, you can use the VGLUE command to glue the volumes. If you mesh them, the mesh will be matched at the interfaces

Hello at first thanks for your help. My simualtion is running now with partially good results. For the layer one, which all the pictures refer to, i calculated a stress in x-direction of 223,5 N/mm^2 and in y- direction of -18,9 N/mm^2 with the Classic Laminat Theory. The stress in z-direction...

Hi now my simulation is running. I was on the right way but my ANSYS version has a mistake; on another PC it works! Thanks for your help!

Is that right what I meant? Thanks

Thanks that means it would be better if i create not the whole volume. I should better create a a hollow cyclinder with a wall thickness of about 0, so that it's like an curved area and mesh this area with the shell element. Thanks

Here is the file. Thanks!http://files.engineering.com/getfile.aspx?folder=ab422fa9-c87c-4030-aa7f-8f330ea0670c&file=output.inp

To the nodes: here i plotted all nodes first sorted by the z- coordinate (at the interfaces at z = 30 and z = 230) and then sorted second by x and third by y. In my opinion there are no double elements. What do you...

Hi, here's a picture of the mesh with the three glued volumes in the background. I glued before meshing. By meshing with MeshTool i use the following settings: Element Atrributes: Global Smart Size: On Mesh: Areas Shape: Tri Free: On Then i pick one area and go to PickAll an Mesh the Volume. I...

Hi i'm running a static strucutral analysis. Unfortunately i have no experience with modal analysis and my benches fail.

One thing i have forgotten: if i execute the List-> Nodes command only nodes until Numer 20216 are shown but the negative pivot term is at node 30338. I don't understand that. Anybody? Thanks a lot!
