Development of concurrent engineering system for design of composite structures

This paper explains the development of a concurrent engineering system for the design of composite structures. The concurrent engineering system is de veloped to meet the demand for the better quality products with lower produ ction cost and time. In this study, to compose the architecture of concurre nt engineering system, the commercial and non-commercial programs related t o design and analysis of composite structures are surveyed and classified. The concurrent engineering system includes various design modules such as d esign/analysis of composite structures using CLPT and finite-element method (FEM), buckling and postbuckling analysis, then-no-elastic analysis of car bon-carbon composite and optimum design using expert system. For the integr ation and management of softwares, a graphic-based design environment that provides multi-tasking and graphic user interface capability is built.
