Diagram of a structure featuring plastic hinges. In the structural engineering beam theory, plastic hinge is the deformation of a section of a beam where plastic bending occurs. [1] In earthquake engineering plastic hinge is also a type of energy damping device allowing plastic rotation [deformation] of an otherwise rigid column connection. [2]
Plastic Bending Stress Distribution. Plastic bending [1] is a nonlinear behavior particular to members made of ductile materials that frequently achieve much greater ultimate bending strength than indicated by a linear elastic bending analysis. In both the plastic and elastic bending analyses of a straight beam, it is assumed that the strain ...
In reinforced concrete structures, the damage state variable quantifies the crack density in the plastic hinge zone; [1] in unreinforced concrete components and steel beams, it is a dimensionless measure of the crack surface; [2] in tubular steel elements, the damage variable measures the degree of local buckling [3] The LDM evolution laws can ...

Further increment in load does not increase the moment at the points where the plastic hinges are formed. The increased load increases the moment in the less stressed sections of the beam; hence due to this, further plastic hinges are formed. This process of shift of application of moment in the beam is termed as moment redistribution in a beam ...
