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).
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.
This phenomenon is called elastic deformation. This behavior in materials is described by Hooke's Law. Materials behave elastically until the deforming force increases beyond the elastic limit, which is also known as the yield stress. At that point, the material is permanently deformed and fails to return to its original shape when the force is ...
the ability of material to return to it's original shape after being stretched or compressed
The strains are small and within the elastic limit. The surfaces are continuous and non-conforming (implying that the area of contact is much smaller than the characteristic dimensions of the contacting bodies). Each body can be considered an elastic half-space. The surfaces are frictionless.
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 ...
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.
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 ...
