Knowledge Based Expert System for Laminated Composite Strut Design

摘要

A knowledge based expert system for the design and analysis of compositelaminated struts is described. This system is part of a composite design expert (CODEX) system that not only performs analysis and design of composite laminated plates and struts, but also incorporates the modeling of uncertainties of information, definition and decision when assessing competing designs. The analysis part of the system is based on a minimum weight optimization that satisfies the failure criteria of local buckling, overall buckling and maximum strain or maximum stress. Available in the system for analysis and assessment are seven types of strut shapes, six composite materials and aluminum alloy. Examples of strut design are carried out and assessed using this system.
