Expansion of thin cylinder over time in Abaqus
Expansion of thin cylinder over time in Abaqus
(OP)
I need to model a balloon like structure that must expand at a certain rate per second.
I've looked at applying pressure internally on the cylinder but I am not able to control the displacement rate this way.
I've also looked at applying a displacement through boundary conditions but I am not getting the results I want.
As it is a cylinder I am finding it difficult to apply displacement equally around the whole surface.
Does anyone know if this is possible and if so any tips would be appreciated

Thanks

RE: Expansion of thin cylinder over time in Abaqus
Also see if you can use the control volume approach where your cylinder can be "inflated" by applying a constant pressure. You can control the mass flow rate and thereby control the pressure.
