Question

During a stress-strain test, the unit deformation at a stress of 35 MPa was observed to be 167 x 10^-6 m/m and at a stress of 140 MPa it was 667 x 10^-6 m/m. If the proportional limit was 200 MPa, what is the modulus of elasticity? What is the strain corresponding to the stress of 80 MPa?

Step 1

The modulus of elasticity, also known as Young's modulus, is a measure of the stiffness of a material. It is defined as the ratio of stress (force per unit area) to strain (deformation in the direction of the force) within the proportional limit of a material. The Show more…
