true stress of 345 MPa is applied. How much will a specimen of this material elongate when a true stress of 415 A tensile te st is performed on metal specimen and it found that a true plastic strain of 0.02 is produced when a MPa is applied if the original length is 500 mm. Assume that the value of 0.22 for strain hardening exponent.

Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.
