WebQuestion: The stress-strain diagram for a steel alloy having an original diameter of 0.5 in. and a gauge length of 2 in. is given in the figure. Determine approximately the modulus … WebModulus of Resilience. In the elastic limit, the maximum amount of energy that can be absorbed by a material per unit volume without creating any permanent deformation is called Modulus of Resilience. It is proportional to the area under the elastic portion of the stress-strain diagram. 1.
