Hi all,
I am working on simple axisymmetric model where two objects come in contact(friction less) to face the load normal to the contact.
Two objects are highly deformable bodies(E=0.69MPa) subjected to compressive pressure 1.2Mpa normal to the contact. deformation can be expected more than 60%.
Because of this, high penetrations and overclosures are occuring during simulation, and the solution is getting terminated.
How can i control the solution ? I already used the following
*Contact controls, Automatic tolerances
*CONTROLS, ANALYSIS = DISCONTINUOUS
*Controls, parameter=time incrementation
20, 10, 12, 30, 10, , , , ,
How can i control the penetrations and overclosures ????
I even tried to use a membrane(E= 1Mpa) between the bodies of to avoid contact difficulties, but still the problem persists....
Any help would be greatly appreciated !
Thanks and regards,
krishna
