we all know the linear hookes law as f=kx where f is the force applied on a spring(adsbygoogle = window.adsbygoogle || []).push({});

and x is the displacement and k is the spring stiffness.

All springs need not behave linearly. suppose a spring behaves non linearly

What is the theory that calculates the deflection for a non linear spring when

a force f is applied.

Basically i believe non linear finite element analysis is based on this non linear

spring theory.

in a non linear spring f will not be proportional to x but may be proportional to

square of x or cube of x or some power of x.
