Plastic moment. In structural engineering, the plastic moment (M p) 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 ...
In structural engineering, the choice between utilizing the elastic or plastic (full moment) strength of a section is determined by the specific application. Engineers follow relevant codes that dictate whether an elastic or plastic design approach is appropriate, which in turn informs the use of either the elastic or plastic section modulus.
t. e. In physics and materials science, plasticity (also known as plastic deformation) is the ability of a solid material to undergo permanent deformation, a non-reversible change of shape in response to applied forces. [1][2] For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes ...
Plastic hinge. 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]
Deformation (engineering) Compressive stress results in deformation which shortens the object but also expands it outwards. In engineering, deformation (the change in size or shape of an object) may be elastic or plastic. If the deformation is negligible, the object is said to be rigid.
Yield (engineering) In materials science and engineering, the yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning of plastic behavior. Below the yield point, a material will deform elastically and will return to its original shape when the applied stress is removed. Once the yield ...
