Material Selection

A wide variety of engineering applications make use of different materials, depending upon their usage. The materials used in civil engineering vary in their properties such as strength, ductility, brittleness, and creep strength. Depending upon the application and external loading conditions, an engineer must make a wise decision for material selection. A wrong decision would fail in its functionality.
