WebA hyperelastic or Green elastic material [1] is a type of constitutive model for ideally elastic material for which the stress–strain relationship derives from a strain energy density function. The hyperelastic material is a special case of a Cauchy elastic material . For many materials, linear elastic models do not accurately describe the ... WebThis property can be defined by the formula below: = L / L. What is strain formula? Answer: The volumetric strain is the change in volume divided by the original volume. The change in volume is the difference between the final volume (V 2) and the initial volume (V 1). The strain can be found using the formula: S = -0.950.
