A rod subject to an axial load (Figure) will be deformed, as shown in the stress-Strain curve
Question:
A rod subject to an axial load (Figure) will be deformed, as shown in the stress-Strain curve in Figure. The area under the curve from zero stress out to the point of rupture is called the modulus of toughness of the material. It provides a measure of the energy per unit volume required to cause the material to rupture. As such, it is representative of the material’s ability to withstand an impact load. Use numerical integration to compute the modulus of toughness for the stress-strain curve seen in Figure.
