Multi step analysis in FEA

thread1630-494366

Multi step analysis in FEA

Multi step analysis in FEA

(OP)
Hello Everyone,

I am running a multi-step analysis for a drivetrain. The first step is used to create a contact between gears by controlling rigid body motions and the second step is used to apply the drive torque.

The question I have is will the stresses that are generated in the first step propagate to the second step or the second step starts with zero stress?

Regards

RE: Multi step analysis in FEA

Are you talking about Abaqus ? Is geometric nonlinearity enabled ? Is plasticity defined ? Make a simple test to check how the results are carried over to subsequent steps.

RE: Multi step analysis in FEA

Hello, yes. Generally in ABAQUS contact interactions defined in the initial step propagates to the next step
