ABSTRACT
The process of structural design of a product has evolved over a long period and arguably there is no set procedure for a design problem; it is an art, yet certain set patterns and key features can be associated with it. Design is a very common term in today's life. It is often used in association with some other terms, for example, graphic design, fashion design, content design, web design, structures design, and so on. Depending on the context, it takes different meanings in different fields. A structure is designed to meet certain functional requirements. For any structure, the most common design requirement that comes to our mind is strength. The configuration of the structure has to be such that the stresses and strains under the design loads are under certain limiting values and material failure does not occur. There are many cases of structural applications, where design requirements are stiffness dependent.
