Bolted Joints in a Laminated Composite Strut Design Expert System

摘要

A knowledge based expert system (for the design and analysis of compositelaminated struts) is part of a composite design expert (CODEX) system that not only performs analysis and design of composite laminated plates and struts, but also assesses competing designs. The analysis part of the system is based on a minimum weight optimization that satisfies the buckling failure criteria of local and overall buckling, and a stress/strain failure from a choice of maximum strain, maximum stress Tsai-Hill of Tsai-Wu failure criteria. The strut optimization expert system is extended to incorporate bolted joints analysis. Examples of strut design are carried out and assessed using this system. The system is shown to be powerful enough to provide solutions to design analysis and assessment of competing designs using composite materials.
