stress-strain
Force per area-elongation
Stress-strain describes the relationship between the force applied to a material and its resulting deformation.
A stress-strain curve or diagram plots this relationship, revealing how materials behave under load—whether they stretch elastically, deform permanently, or fracture.
Engineers use stress-strain data to determine material properties like stiffness, yield strength, and ductility.
