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.

Case Study Calculate the Tensile Toughness Tensile toughness measures the total energy absorbed prior to fracture and is different from fracture toughness and impact toughness. Fracture toughness measures the resistance to fracture when a flaw (i.e. crack) is present in the material. Since it is nearly impossible and costly to manufacture materials with zero or near zero defects, fracture toughness is a major consideration for all structural materials. Impact toughness measures a materials ability to withstand an impact blow (i.e. high strain rates) and is particularly important in assessing the ductile-to-brittle transition behavior (more details later). Impact toughness is also commonly referred to as notch toughness. The tensile toughness can be estimated using the stress-strain curve by measuring the area under the curve (both the elastic and plastic regions).
