For stresses that exceed yield, refer to article plastic bending.
After a structural member reaches a sufficiently high condition of plastic bending, it acts as a Plastic hinge.
The large deflections and stiffness changes usually associated with plastic bending can significantly change the internal load distribution, particularly in statically indeterminate beams.
Elementary Elastic Bending theory requires that bending stress varies linearly with distance from the neutral axis, but plastic bending shows a more accurate and complex stress distribution.
"' Plastic bending "'occurs when an applied moment causes the outside fibers of a cross-section to exceed the material's yield strength.
The limiting "'plastic bending "'strength M _ r ( see Plastic moment ) can generally be thought of as an upper limit to a beam s load carrying capability as it only represents the strength at a particular cross section and not the load carrying capability of the overall beam.
