A crack has been discovered along the edge of a reinforcing rib in titanium housing. The rib is 0.5 inches thick and 4.0 inches wide. The crack extends completely through the thickness and is about 1.20 inches long. If the housing is subjected to static loading only, and the maximum estimated loading produces a tensile load along the rib axis of 50,000 Ib, should the housing be removed from service? The housing material exhibits a yield strength of 150 ksi and a plane strain fracture toughness of 50 ksi in1/2.

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.
