Plastic Deformations

It is essential to understand how structural members behave under plastic deformation when the bending stress exceeds the material's yield strength. This state of deformation permanently alters the shape of the member, in contrast to the linear elastic behavior observed before yielding. The strain at any point in the member is expressed in terms...

For pure bending, when maximum stress exceeds the yield strength of the member's material, it undergoes plastic deformation.

The strain at any point in the member is expressed in terms of maximum strain. For plastic deformations, the neutral axis of the member may not pass through the centroid of the member.

Here, the neutral axis ...
