    Noisy stress distribution Abaqus explicit

    Hi all, I have problem after my explicit simulation finishes. It is a quasi static simulation and in the second step I have ALLKE << ALLIE I use mass scaling to reduce the calculation time At the end, on one part, the stress I get is very noisy and discontinuous. I tried to refine the mesh but...

    Seal compression into groove in 3D

    Thanks for the advice I did not remember this help section. I will try to add some compressibility and relaunch to see. If I refine the mesh this leads to huge time increments that's why I try to avoid it What is it you define as "softened contact" ? Is it using penalty contact method or linear...

    Seal compression into groove in 3D

    Hi Dave442, For material properties I have Neo Hookean rubber so C01 = 0.73 and D1 = 0.001 which takes into account incompressibility

    Seal compression into groove in 3D

    Hi all In one of my 3D analysis, I have to compress a seal into a groove which is formed between 2 parts First step is ok, push the ring into the groove 2nd step is to remove the "pusher", ok also But the third step ... When I compress the upper part, at some point the contact "explodes"...

    Abaqus explicit axissymetric - &quot;hybrid&quot; surface definition

    Hello everyone In one of my Abaqus/explicit analysis, I have to use a pressure cavity. The analysis is axisymmetric. To define my pressure cavity I created a surface in the assembly module, because the surface comes from MULTIPLE parts The problem is that Abaqus explicit does not compute at...
