This equation is applicable when there exists negligible dislocation movement.
This equation is applicable when there exists negligible dislocation movement. Integrating this equation with respect its dimensionless variable over the applicable range gives an energy density known as the resilience. The inverse of the constant appearing in this equation is in general a rank-4 tensor known as the compliance, which is the inverse of the 21-component (*) stiffness, which is in turn this equation's constant of proportionality. This law is approximately valid up to the proportional limit, but exact only up to the elastic limit, above which plastic deformation occurs. Stating that, in an isotropic material, the elastic modulus times the strain is equal to the stress, FTP, identify this law of physics named for its British formulator, often used to model the behavior of springs.
