When a material reaches its ______________, deformation of a material becomes permanent.

Question

Quizplus · Accepted Answer

Yield strength is the point on a stress-strain curve where a material changes from elastic deformation to plastic deformation, meaning that any further stress applied to the material will result in permanent deformation. The ultimate strength is the point of maximum stress on the curve, but permanent deformation may or may not occur at this point depending on the material's behavior. The elastic modulus is a measure of a material's stiffness and is not directly related to the point of permanent deformation.
