Find the total toughness energy for a metal that experiences both elastic and plastic deformations. The modulus of elasticity is 107.2 GPa, and elastic deformation terminates at a strain of 0.009. For plastic deformation, assume that the relationship between stress and strain is described by T = 1.66xKn, in which the values for K and n are 1453 MPa and 0.175, respectively. Furthermore, plastic deformation occurs between strain values of 0.009 and 0.67, at which point fracture occurs

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.
