Stability optimization of cantilevered columns subjected to both conservative and nonconservative loads is studied. Internal and external damping is taken into account. The optimization problem of volume minimization by constant critical load is solved numerically by using finite elements and sequential linear optimization. It is shown that this problem is equivalent to maximization of the critical...
The Galerkin element method (GEM), which combines Galerkin orthogonal functions with the traditional finite element formulation, has previously been applied successfully to the vibration analysis of damped sandwich beams, and an improved iteration method was developed for its eigen solution. In the current paper, this promising method is extended to the vibration of damped sandwich plates. A quite...
