The modulus of resilience is joules per cubic meter.Explanation:At first we assume that allow behaves elastically, then the formula for the modulus of resilience (), measured in joules per cubic meter, is:(Eq. 1)Where: - Yield strength, measured in pascals. - Modulus of elasticity, measured in pascals.If we know that and , then the modulus of resilience is:The modulus of resilience is joules per cubic meter.
