Toughness can be measured in many ways. Unit of the Modulus of Resilience. It can also be defined as the strain energy stored per unit volume of the material upto fracture. By definition, modulus of toughness is the energy, per unit volume, required for breaking a particular solid material under tensile testing. We demonstrate the principle by fabricating a composite of two constituents: a matrix of low elastic modulus, and fibers of high elastic modulus, with strong adhesion between the matrix and the fibers, but with no sacrificial bonds. This two-phase morphology is responsible for the viscoelastic mechanical properties, the stress–strain behavior, the tensile strength at yield, and the post yield hardening. Note that the units of the modulus of resilience are the same as the units of strain energy density, which are psi in US Customary units and Pa in SI units. Generally, greater the toughness, greater will be the toughness. It is the area under the stress-strain curve upto fracture point.
