Description
Determine the deflection of a cantilever beam under a torque applied to its free end. The beam has a length of 100" and a rectangular cross section of dimensions 2"X1".

The material is nonlinear elastic (defined by a stress-strain curve).

Material Properties
Poisson's ratio = 0.
Restraints and Loads
The bar is fixed at one end and a torque is applied at the other end as follows:
