tensile test is performed to determine the parameters strength constant C and strainrate sensitivity exponent m for a certain metal. The temperature at which the test is performed = 500°C. At a strain rate = 10/s, the stress is measured at 140 MPa; and at a strain rate = 150/s, the stress = 280 MPa. (a) Determine C and m. (b) If the temperature were 600°C, what changes would you expect in the values of C and m?

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.
