How Do You Calculate Resilience From A Stress-strain Curve?

How Do You Calculate Resilience From A Stress-strain Curve? Like the unit of tensile toughness (UT), the unit of resilience can be easily calculated by using area underneath the stress–strain (σ–ε) curve, which gives resilience value, as given below: Ur = Area underneath the stress–strain (σ–ε) curve up to yield = σ × ε Ur
