Abstract
Optimization of conical shells under static or dynamic loads is treated herein. Volume minimization subject to constraints on either allowable stresses or fundamental frequency and frequency maximization subject to a constraint on volume are studied. Piecewise linear variation in shell thickness is allowed in the study. A numerical procedure incorporating the finite element method and direct search optimization techniques is used. Results indicate that considerable saving in material and elevation in frequency are possible.
