The lowest stress in a material (less than the maximum attainable stress) at which the material begins to exhibit plastic properties; beyond this point an increase in strain occurs without an increase in stress.

A measure of the amount of stress needed to permanently deform a material. When a material is stressed beyond its yield point or elastic limit, it will not return to its original shape and size when the stress is removed. The yield point of a material is slightly higher than its elastic limit.
