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.

Given your understanding of what initiates and controls failure in materials, which of the following will reduce the failure strength or lifetime of a test piece and why? a. (more than one answer is possible for this question. marks will only be awarded for the question if all the correct options are selected (i.e. 'all or nothing' marking scheme). b. LUS C. d. Increasing its volume, greater likelihood of critical defects Decreasing the loading frequency, the material will be at peak stress values for longer Decreasing the grain size, more grain boundaries to initiate failure Increasing the difference between the maximum and minimum stress values, as this affects the stress concentration factor Recent M Raising the temperature above the BDTT, more plastic deformation in the lattice will cause it to fail faster G
