This paper discusses shape optimization problems for elastic shafts under torsion us-ing genetic algorithms (GA) coupled to the boundary element method (BEM). A GA is proposed to evolve the shape optimization involving the objective function that minimizes the area of the cross-section where the constraint imposed is a minimum value of torsional st...

... infeasible, all of these values are very close to the exact solution with respect to both the area (314.159) and the torsional stiffness The Figure 4 shows the final shape of the shaft for the best feasible solution found in the first run. The Figure 5 shows the final shape of the best infeasible solution found in the sixth run. The red color in both cases corresponds to the exact solution whereas the blue color indicates the solutions found by the GA. ...

In the current work, we consider the inverse conductivity problem of recovering inclusion with one measurement. First, we use conformal mapping techniques for determining the location of the anomaly and estimating its size. We then get a good initial guess for quasi-Newton type method. The inverse problem is treated from the shape optimization poin...
This paper is concerned with the numerical implementation of the dual boundary element method for shape optimal design of two-dimensional linear elastic structures. The design objective is to minimize the structural compliance, subject to an area constraint. Sensitivities of objective and constraint functions, derived by means of Lagrangean approac...
