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.

How are the Normal and Shear Stress Components used?
Assume a matensetic steel (Kic = 110MPavm) whose fatigue crack growth rate is given on the attached sheet. A large steel plate with a central crack of length 2.5mm was designed to withstand an instantaneous remote tensile over-load of twice the maximum load. If the plate is subjected to a cyclic loading of 0 = = 158 [1 + coswt] MPa How many cycles can the piece safely withstand?
1. Please draw a typical tensile test curve for low carbon steels and mark the four stages and list their names (use critical points on the curve to help you identify the start and end points of the four stages). 2. Show the yield, ultimate tensile strength and fracture points, as well as yield and ultimate tensile strength on the curve. 3. Please draw the load and unload curve for a stress level causing the low carbon steels to experience elastic deformation only. 4. Please draw the load and unload curve for a stress level causing the low carbon steel to experience permerment deformation, and identify both elastic and plastic strain on the drawing after unloading.
Which is the correct definition of elastic deformation? The behavior of a material when its size changes by the addition of heat. The behavior describing a material's shape change under load that is self-reversing after the force is removed, so that the material returns to its original shape. The behavior describing a material that deforms when subjected to stress and does not return to its original shape when the stress is removed resulting in permanent deformation. Deformation caused by cleavage, where the material is actually pulled apart across atomic planes within the crystals or along the grain boundaries.
