Modulus of Resilience

The modulus of resilience measures a material's ability to absorb energy and deform elastically without permanent damage. Think of it as how much "bouncing back" a material can handle when loaded. It is calculated as half of the material's yield strength multiplied by the elastic strain (the deformation within the elastic limit). A higher modulus of resilience indicates a material can absorb more energy during elastic deformation before it yields or gets permanently deformed, making it valuable for applications where energy absorption and elastic performance are important.
