Write 4 page essay on the topic Materials Analysis/Selection.
Mechanical engineer selects on metal material most of the time.
During the selection of metals, their properties most analyzed are the metal mechanical properties, fatigue strength, fracture toughness, thermal properties, magnetic properties, fabrication properties, and environmental properties, gas, and liquids properties. Mechanical factors of a metal are mention in terms of strength, ductility, young modulus, hardness, poisons ratio, anisotropy, creep, and density.
A heat and wear resistant ceramic coating is required for a titanium alloy part. Using CES level 2 choose a material that might be suitable for the application. Discuss your selection methodology and include details of any CES work you carry out.
This feature measures materials ability to resist elastic deformation when subjected to a load. A material stiffness is made concerning basis on young’s modulus number. High values mean the material is stiff.
This is a material’s ability to resist failure. Strong materials need subjecting to massive loads to undergo permanent elastic deformation. This property mentions type of failures a material can go through. Metals and wood yield as a means to failure while materials considered brittle undergo fracturing
The measure of a materials resistance to breaking into two split parts is known as toughness. During breaking, energy absorption takes place. Sizes of part determine magnitude of energy absorbed. Toughness is per unit of force absorbed. For tough materials, high energy level is required to destroy it or break it.
Materials experiencing strain are deemed to fail at some point under increasing loads. The measure of amount that a material can sustain strain is termed as ductility. Elongation of material is evident in very ductile materials. In contrast to brittle materials which portray in them minute elongation levels due to reasons that they do not deform plastically.
Heaviness verse size is the determinant factor for a material’s density.
