Proportionality limit Up to this amount of stress, stress is proportional to strain (Hooke's law), so the stress-strain graph is a straight line, and the gradient will be equal to the elastic modulus of the material. Elastic limit (yield strength) Beyond the elastic limit, permanent deformation will occur.
The material's elastic limit or yield strength is the maximum stress that can arise before the onset of plastic deformation. Its SI unit is also the pascal (Pa). Its SI unit is also the pascal (Pa). Overview
Elastic deformation is reversible, meaning that the material returns to its original shape after the load is removed. ... The point E is the elastic limit or the ...
In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring.
Elastic energy is the mechanical potential energy stored in the configuration of a material or physical system as it is subjected to elastic deformation by work performed upon it. Elastic energy occurs when objects are impermanently compressed, stretched or generally deformed in any manner.
Elastic limit (Yield surface). The elastic limit is defined by a yield surface that does not depend on the plastic strain and has the form =. Beyond the elastic limit. For strain hardening materials, the yield surface evolves with increasing plastic strain and the elastic limit changes.
Hugoniot elastic limit in the p-v plane for a shock in an elastic-plastic material. For shocks in solids, a closed form expression such as equation cannot be derived from first principles. Instead, experimental observations [15] indicate that a linear relation [16] can be used instead (called the shock Hugoniot in the u s-u p plane) that has ...
The elasticity at a point is the limit of the arc elasticity between two points as the separation between those two points approaches zero. The concept of elasticity is widely used in economics and metabolic control analysis (MCA); see elasticity (economics) and elasticity coefficient respectively for details.
