I try to simulate the thermoforming of a PMMA sheet in Ansys 14.
Having done some research I used the hyper-elastic Mooney-Rivlin material model using the following parameters:
C10 = -0,03
C01 = 0,453
My first simple simulation (in Ansys transient structural) only contains a rectangular sheet which is fixed at the green highlighted border areas and a single pressure load.
The simulation only coverges if the pressure load is very low (e.g. 1E-5 MPa).
I enabled the "large displacement" setting, but if I try to simulate a higher pressure, the simulation does not converge.
Can anybody suggest what I need to change in order to get the simulation to converge?
Thanks in advance!
