Resilience is the measure of a material's ability to absorb energy elastically. Resilience can be viewed graphically on a material's stress and strain curve. It is measured along the linear portion of the curve, before material deformation and fracture occurs. Resilience is often denoted by the variable "U" with a subscript "R." Physical information such as the yield stress and the strain of the material at the yield stress is required to make this calculation.

1
Find the material's strain at the yield stress. This value will be denoted with a lowercase Greek epsilon and the subscript "y."
-
2
Find the materials yield stress. This value will be denoted with the lowercase Greek sigma and a subscript "y."

3
Multiply the values from steps 1 and 2 together and divide the total by two. The result of this calculation is the modulus of resilience.
