Plastic moment
In structural engineering, the plastic moment (Mp) is a property of a structural section. It is defined as the moment at which the entire cross section has reached its yield stress. This is theoretically the maximum bending moment that the section can resist – when this point is reached a plastic hinge is formed and any load beyond this point will result in theoretically infinite plastic deformation. In practice most materials are work-hardened resulting in increased stiffnes… WebbDownload scientific diagram Plastic moment and ultimate moment are calculated by MATLAB and ABAQUS software [12] from publication: Seismic performance of box-plate, …

WebbA Class 2 cross section corresponds to one which can reach its plastic moment resistance but solely provide limited rotation capacity due to elastic–plastic local buckling (M u > M pc). Finally, for a Class 1 cross section, the plastic moment resistance can be developed with sufficient rotation capacity to allow redistribution of moments in the steel frames ( …

This is termed a plastic hinge which is the basis for plastic analysis. At the plastic hinge, stresses remain constant, but strains and rotations can increase.
