Pressure loading in Abaqus when the boundary surface is changing 2

[ravi956]

How to model uniformly distributed pressure on the curved surface. The surface area is changing throughout the simulation process. how model this.

 

[Mustaine3]

By using a nonlinear procedure and applying a pressure load.

 

[FEA way]

The OP is asking about more complicated case of changing surface with apllied load. He wants it to update during the process of micropipette aspiration (see his previous thread where the problem is discussed). Normally this would require subroutines but my idea is to simulate some small part of the process (so that first stage of deformation occurs), import results to new explicit analysis, apply pressure to new (deformed) surface, run the simulation and repeat the process.

 

[Mustaine3]

Then he shouldn't create this new thread with this generic question...

Actually, I am not applying the pressure load as the micropipette aspiration. It is slightly different like what I mentioned above. I am planning to do this using the user subroutine. I am new to subroutines can you please help how to start.

sorry, Mustaine3 I am new to this foram. so I thought it is ok to start a new thread.

Thanks
