In many engineering products, the shape of a design can                    have considerable affect on performance.  The performance of                    dams, transmission towers, fillets, aircraft, and automobiles                   are all affected by their geometric shape.  Shape optimal                       design can be applied to any structures for which a                             mathematical model exists.  The basic approach in shape optimal                 design is to choose a set of design variables that defines the                  shape of the structure.  Changes in the geometric structure can                 then be related via changes in the finite-element mesh to                       changes in the design variables.                                                     The Principal Investigators propose to develop a new                       approach for shape optimization of structures.  The design                      variables will be represented as fictitious loads on the                        structure.  The displacements produced by these fictitious                      loads are added to the finite-element mesh to obtain a new                      shape.  This new approach is computationally superior to                        the standard approaches and allows the possibility of physical                  interpretation of optimality criteria for a class of                            problems.                                                                            This research is a joint research project with Subramaniam                 Rajan at Arizona State University who is being funded                           separately under grant DMC-8614205.
