Elasto-plastic deformation 2

[BATUHAN]

I need to calculate the deformation of simply supported beam exposed to distributed load in elasto-plastic analysis? I would like to ask if is there any analytical methods to do it.
Thanks for your interest

This may be fit your need. Link This one too. Link

Plastic rotations (or simply rotations) can be found by integrating curvature along the member. To include the in-elasticity behaviour of the material you just have to calculate the actual curvature of the section and then use methods such as moment-area or conjugate beam to find rotation and displacements.

I hope the following figure clarifies the starting step. The specified analysis methods, I assume, you will be familiar with and can easily calculate the rotation and displacement using the plotted M/EI diagram.
