Hey there,

I have 4 point bending setup 2D COMSOL model. I want to model 4 point bending constant deflection/strain test. I have a rectangle (substrate) and I put 2 dots on the rectange representing loading clamps and 2 dots at the outer side representing support clamps.

1) How can I add load as a Force (F) in Newtons to increase until midspan deflection reaches a certain number lets say 0.5 mm ?

2) I am trying to simulate setup as second picture, Can anyone help me with this?

I appretiate any help regarding this or perhaps if anyone have already done something similar and willing to share the model?

Thank you.
