Abstract: - Nowadays, high demand for light weight durable structure in many industries like automobile, mechanical, aeronautical ,structural ,.etc. Hence structural optimisation has considerable attention to satisfy industrial goal. In early days, structural optimization was restricted to size optimization. The efficiency of size optimization is less compared to shape & topology. In this research we concentrate on shape optimization for typical practical problems under stress & Area based constraints. Shape optimisation involves finding the best profile for a structure under various constraints imposed by the requirements of the design. The objective may be to minimize weight or maximize mechanical performance like stress minimization, high stiffness, fracture strength ,.etc. In any optimisation problems locating globally optimal structure is a difficult, requiring sophisticated optimization procedure. But using global optimization algorithms like Genetic & Simulated Annea!
ling algorithm we can easily locate global objective functions. The algorithm was developed in ANSYS Parametric Design Language
