The strain rate, or the rate at which deformation occurs, can influence the stress-strain behaviour of materials. Higher strain rates generally lead to higher flow stresses and less ductility .

As plastic deformation progresses, the material may strain harden, requiring higher stresses to induce further deformation. This is represented by the increasing slope of the stress-strain curve after yielding .

There are different types of strain, including engineering strain (based on initial dimensions) and true strain (based on instantaneous dimensions). True strain is more accurate, especially for large deformations .

Strain is defined as the ratio of the change in length (or dimension) to the original length (or dimension) of the material under applied stress . It represents the amount of deformation experienced by the material.
