Hello !
I have a question.
if I put pressure on the model, do material properties change ? as the elasticity. why does frequency change
Can someone help me ?

Hi
that depends what you are modelling, you might be in "solid" then you can get stress stiffening, in certain cases, but for that you need to combine a stationary stres analysis and use that as the starting point for an eigenfrequency analysis
But yu can also have a pressure dependent material that depends on the material you are using and the physics you have selected

Good luck
