Beam Bending Stress

Click For Summary

The discussion focuses on calculating the residual stress in a beam after bending, using a linear hardening model to predict stress and strain. The strain and stress equations are defined based on the beam's geometry and material properties, including yield strength and Young's Modulus. The springback effect is accounted for in the relationship between the bending radius and the resulting radius after unloading. The residual stress is determined by the difference between the stress during loading and the stress after unloading, with analytical calculations being emphasized over numerical methods. Participants also discuss the behavior of stress-strain curves and the implications of negative stress values after unloading.

Thanks, I was confused because of the equations I was unfamiliar with and those functions for Sigma(Stress). Do you have any other worked-out examples pdf that I could follow? Can you suggest any other references please? That would be such a huge help.

What are the dimensions and material properties of the pipe? Also, to which bending radius do you need?

What have you worked out up to now? In order to have a proper insight of the results it is better to understand well the theory and also its limitations instead of just “using the formulas”.
