%X This paper develops the shape optimization of a body, which is hanged and subjected to body forces. The geometry of the body is modeled using parametric curves B-Spline. The shape optimization is carried out modifying the boundary of the body based on the stress level calculated via Finite Element Analysis (FEA). Traditional evolutive rules are used for the optimization process; however, the method of boundary modification in the optimization process is neither traditional nor trivial. Unlike most shape optimization methods, which only use the information of boundary points in a isolated way, in this approach the geometry boundary is modified considering both points and neighborhood information.
