Strain

Hello world !
I being a relatively recent Comsol newbie, evaluation stage.
I am adressing a curious outcome in the Structural Mechanics module, 2D. Beginning with a simple system like a polymer foil 20 um thick 100 um wide.
The left side of the foil I set it fixed, whereas the right side is loaded with a force Fx= 10000.
After simple meshing & solving the outcome is a strained system with a ~ 5% strain.
Then I double the applied load (Fx=20000) and (!) the outcome is the same: the system strain is 5%.
When the load is increased 5 times (Fx=50000), then the system is strained again to 5% ! : - s !
I am doing something wrong? I would expect that for a load double, the strain would double as well.
