Yes, the problem is exactly the same, Can you try to make some benchmark to see if you obtain the same result?

Hello to all forum, I'm just starting to testing the capabilities of LS-DYNA and make a comparison with ABAQUS. LS-DYNA have also an implicit solver and I just made a comparison with ABAQUS implicit. Ther result are the same but the calculation time is 8min for and LS-DYNA and 1h and 40min for...

Hello to all forum, there is someone that can give me or said where find the fatigue curve about Delrin 111P NC010 or other kind of Delrin? On Dupont web site there aren't these information Regards Stefano

Hello to all forum, Thre is someone that can explane me how to import in ABAQUS\CAE a mesh created on Hypermesh? Regards

Hello to all forum, I use a beam to simulate a pretension of bolt. In particular I made the nut and bolt head with rigid body and connect the two control node with a beam. After I give a temperature variation on beam and I can simulate the pretension. After I try to evaluete the contact force...

Hello to all forum, I'm starting to ask a question a bout creep simulation and analysis of plastic. To simulate a creep behaviur of plastic material as delrin, Nylon...after 800h of creep I use the law epsilon=A*sigmaexpn*t. With this kind of law I don't consider primary zone of creep but only...

Hello to all forum, I'm asking for a question about plotting result. In the step manager I asked the field and history output beahind: *OUTPUT, FIELD *NODE OUTPUT U, RF, *NODE OUTPUT, NSET = Boundary_node_left RF, TF, *ELEMENT OUTPUT S, PE, *NODE PRINT, NSET = Boundary_node_left, FREQUENCY = 1...

Hello to all forum, There is some one that can said me the command to simulate the plastic material or somthing to similar as Nylon, Delrin... In some tutorial I see that somethimes the Nylon or other material are treated are steel using for example the command: *ELASTIC, TYPE = ISOTROPIC ...

Thanks a lot for your help I try to doing it and now the contact "see the thikness". Keep in touch on forum Jacopo Verani

Thk, I see if I insert small sliding in contact pair keyword also if I use node to surface formulation the thikmess is considered, but how can I see when I chose surface to surface or node to surface iteraction?How can chose one or other one?

Hello, to all forum, I need help about contact shell to shell or solid to shell. When I'm going to define the shell surface I use the command behaind: *SHELL SECTION, ELSET=Elset_name, MATERIAL=steel 1 , and don't use the command OFFSET so I have the reference surface coincident with...

Hi to all forum, I need to knoe the fatigue curve a bout some polymer as Delrin511P delrin111p and other kind of plastic material. Is there some one can give me these information? Is there some web site specialized in these information? Regards

As the shell is define you can't see the S33 value because the thickness is too small so the value of S33 is ignored because appare less than other value (you can see it on shell theory). If you wont see it you must use 3D model. Another question, Can you said me how can change the average on...

I don't know if is possible see the s33 direction, but you can plot the stress to different section point of the shell, for examplo you can see the value on the middle of the thickness and on the upper and lower face. You must asked on output the section point writing: *ELEMENT OUTPUT 1,3,5 S...

Thx I try to doing a path on XY plot, but when I try to associate the nodes to a new CSYS, that I have previously created, the csys isn't associate. How can associate it correctly? How can I change the average on the result visualization? There is someone can give me a creep power law for Delrin...
