Computer Program (OPTCOMP) for Optimization of Composite Structures for Minimum Weight Design.

Abstract

The computer program OPTCOMP can be used to optimize or analyze a composite structure. The program uses an iterative procedure based on optimality criteria to design a minimum weight structure. The response of the structure to the applied loads is obtained by finite element analysis. The design variables are modified during each iteration by using a recurrence relation. The four strength criteria included in the program are maximum stress, maximum strain, Hill's criteria modified by Tsai and Norris criteria. The plate elements can be designed to prevent local buckling. The elements can be linked to have the same sizes if desired. A mixture of composite and metal structure can be designed by suitable definition of material properties. (Author)
