To all
I am thinking about a possible mcad sheet for an hyperelastic material ie a rubber. Attached is a typical curve for such material.
I would like to predict the displacment (of some quantity, maybe stress) knowing the total force to be applied. I am not sure so will be happy to be corrected but is this a non linear problem (gien the shape of the curve)?
Known
- total force to the applied
- a (non-linear) relationship between say strain & stress
Find
The final "state" once all the toal force is applied
I haven't got a clue where to start.
Does the probleme require some kind of iterative solver?
Am I overthinking the whole think?
Any suggestion is welcome
Thanks
