Dear Experts;

I am trying to perform an analysis there are two bars and one edge of these two bars are fixed and pressure applied to the bars.

I created a frictionless support between bar surfaces because they will touch each other. But according to my analysis they pass through each other.

here is the connection;

here is the boundary conditions;

here is the last step which solver could solve.

where am I making mistake or wrong?

what can be the reason for this mistake?

I look forward to your comments and thank you in advance.

Best regards.

Hi

See our courses in contact for a general overview.

In your case make sure you have many substeps (https://www.padtinc.com/2011/11/08/you-dont-wanna-step-to-this-breaking-down-loadsteps-and-substeps-in-ansys-mechanical/),

large deflections on,

and pinbal region is large enough (see here for info: https://www.padtinc.com/2015/11/09/be-a-pinball-wizard-with-contact-regions-in-ansys-mechanical/).

Also set displacement scale factor=1.

 

All the best

Erik

Dear Mr Kostson;

when I applied pinball radius the problem was solved and converged.

I made not any changes Pinball radius I left it as program controlled.

thank you for your suggestion.
