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.

Which of the following are incorrect regarding the crystallinity and mechanical behavior of polymers? a. Strain softening happens in elastomers where the deformation gradually leads to a decrease in stiffness under constant strain rate b. As temperature is reduced, necking behavior of plastic tensile bars completely disappears C. The stress-strain curve slope for totally elastic and brittle polymers is always positive d. Heat treatment always results in enhanced polymer strength, modulus, and brittleness e. Semi-crystalline polymers are heat treated to increase crystallinity and improve strength f.
