Abstract Material selection is an important stage in engineering design. Engineers use various materials with different mechanical properties in building of structures. These mechanical properties include; tensile strength, yield strength, proof stress, Young's modulus, shears modulus of rigidity and ductility amongst others. Material selection increases the performance as well as durability of the engineering component. The expected life, cost, nature of loading and working environment are some of the factors that assist engineers to select materials for particular application. Therefore, engineers and designers must be able to determine the properties of these materials before they use them. Engineers ...
