III-A component is subjected to a cyclic loading at the frequency of once every 5 minutes for 5 years. The cycle is between 220 MPa in tension and 50 MPa in compression. The fracture toughness of the material is 80 MPa√m, Y = 1.12, C = 1.62 x 10-12 (MPa and m) and n = 3.2, and we know that it has initial cracks of length 0.1 mm. At the end of the 5 years, because of the failure of other components, the stresses become 10 times larger. Is the component able to hold the new cyclic loading? If so, for how long? If not, explain.

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.

Question

III-A component is subjected to a cyclic loading at the frequency of once every 5
minutes for 5 years. The cycle is between 220 MPa in tension and 50 MPa in
compression. The fracture toughness of the material is 80 MPa√m, Y = 1.12, C = 1.62
x 10-12 (MPa and m) and n = 3.2, and we know that it has initial cracks of length 0.1
mm. At the end of the 5 years, because of the failure of other components, the
stresses become 10 times larger. Is the component able to hold the new cyclic
loading? If so, for how long? If not, explain.
