Abstract

The essential difficulties with optimization of nonconservative systems are considered. Model problems are used to show that the functions of the optimization problem may be nonsmooth and possibly also discontinuous functions of the design variables. It is further demonstrated that considering a slightly more complicated structural model with damping may simplify design optimization. Using a model with damping, it is possible to pose the optimization problem in the form of matrix inequalities. The resulting problem may then be solved using a barrier method with smooth objective and constraint functions.
