Buckling of a nanoribbon

Dear Users

I’m writing a buckling script for a nano ribbon. but when I apply force or movement, the ribbon doesn’t buckle and it makes some sinusoidal wave instead. I have changed the rate of force and movements several times but the result was not buckling.

Sincerely;
Reza

​is there a question here?
