Hi
I have modelled a cylinder being indented by a rigid hemispherical indenter. The indenter is then retracted in a 2nd step before a 3rd step is implemented to pressurize the cylinder externally.
My problem has been trying to measure the change in volume of the cylinder as the pressure is...
Thanks for yoyur reply mrgoldthorpe.
I managed to obtain a solution using a *Dynamic, Implicit step. This shows the pipeline in the collapsed mode I was expecting to see. Now I'm trying to understand why this works as opposed to the *Static, Riks method I was trying to use before.
Hi,
I am modelling the indenatation and collapse of a subsea pipeline. The hemispherical indenter is modelled as an analytical rigid surface. The pipeline is modelled resting on a perfectly flat seabed which is also analytical rigid.
The displacement of the indenter is moved downwards until...
