Webb13 maj 2024 · What does limit of proportionality and elastic limit mean? The limit or proportionality: ‘the greatest stress that can be applied to an elastic body without causing permanent deformation.’ Elastic limit: ‘the maximum extent to which a solid may be stretched without permanent alteration of size or shape.’ What is a proportional limit? WebbThe proportional limit is the point on a stress-strain curve where the linear, elastic deformation region transitions into a non-linear, plastic deformation region. In other words, the proportional limit determines the greatest stress that is directly proportional to strain.
Elastic limit Definition & Facts Britannica
It is often difficult to precisely define yielding due to the wide variety of stress–strain curves exhibited by real materials. In addition, there are several possible ways to define yielding: True elastic limit The lowest stress at which dislocations move. This definition is rarely used since dislocations move at very low stresses, and detecting such movement is very difficult. Proportionality limit Up to this amount of stress, stress is proportional to strain (Hooke's law), s… WebbTherefore, the difference between elastic limit and proportional limit is, elastic limit is the point at which there is no permanent deformation in a structure or the point at which the body regains its original shape, while the proportional limit is the point at which stress is directly proportional to the strain. hallstand definition
