Optimization is the process of selecting the best possible results among many possible results under given circumstances. Mathematically it is finding the global maxima or minima of a function. This paper concerns with the optimization of a cantilever beam. The governing idea is to r educe the mass of the beam for a given strength. The cross section under consideration is a rectangular one. A Graphical Approach has been adopted to plot SOM equations on Matlab to obtain a common acceptable domain. A traditional method, Johnson’s method was considered to account for fatigue strength of the material and obtain optimum dimensions. Finally COMSOL software was used to topologically optimize the beam.
