Strain Energy Density in Strain Energy Formulas

Strain Energy Density is the energy dissipated per unit volume during the strain-hardening process, is equal to the area enclosed by the ascending branch of the stress-strain curve. And is denoted by U_density. Strain Energy Density is usually measured using the Joule per Cubic Meter for Energy Density. Note that the value of Strain Energy Density is always positive.
