Abstract

An optimization procedure, suitable for combined shape and sizing parameters, is proposed for design tasks requiring linear static, natural frequencies and mode shapes, linearized buckling, and steady state thermal analyses. Advanced applications such as nonlinear and transient problems can also be supported. Design constraints from different types of analyses can be combined in a multidisciplinary optimization. The procedure is implemented in COSMOS/M, a modular finite element analysis program, with a seamless interface with Pro/ENGINEER, a parametric feature-based solid modeling system. Introduction Finite element analysis (FEA) proved to be the most frequently used tool for analysis and design of complex structures. Modular finite element programs provide, beside speed, memory, and storage advantages, an econom
