I want to model pneumatic bending actuator with solid work.This Actuator is made with silicon rubber it mainly have two parts Bottom layer and main body.The bottom layer is material is also silicon and less stiff than main body.when applied pneumatic pressure to actuator it bends.The Below pictures will help to understand.

The researchers of this acuator have already modeled it with dassault systemes Abaqus.But i want to do it with solidwork .

This is the result they obtained with Abaqus. They have a tutorial about modeling this with abaqus(https://softroboticstoolkit.com/book/pneunets-modeling)

I tried to get this with solidworks simulation with sevaral ways,But i failed .. Can Anyone give me a help to simulate this properly  ?
