This is the Phase II SBIR USAF Contract Program for the detailed design, production demonstration of a prototype intelligent knowledge system for the selection of materials for critical aerospace components IKSMAT. IKSMAT was shown to be technically and economically feasible in a Phase I SBIR program, and the development of the prototype was based upon the specification defined in that effort. The IKSMAT system provides multiple-path access to a knowledge base of information vital to the assessment of the suitability of materials for key components, with a software package capable of evaluating and ranking the performance of those materials based upon specific properties andor design- related parameters such as critical flaw size index. Users of the system are able to search for candidate materials for specific aerospace components a utilizing the basic materials and selection processes programmed into the systems, b adding new properties for the existing materials, c adding information for materials, andor d altering the criteria and functional priorities used in rating the materials. The knowledge base for the prototype IKSMAT system was developed to support material selection for seven aerospace components winspar, upper wing skin, lower wing skin, pivotswivel pin, bulkhead, landing gear and fuselage. The Master IKSMAT Database for the prototype was based primarily upon MIL-HDBK-5F, with supplementary data for several sources.
