Rule inferencing and object-orientation for boundary elements mesh design

摘要

In this paper, object orientation and rule inferencing are used to automate the design of boundary element meshes. The work is part of an effort to develop an object-oriented integrated environment for the damage tolerance design of aircraft stiffened panels and other parts such as fuselage lap-joints. An inference domain class library has been developed. Inference domain objects are used to create symbolic representations for the structural configura- tion and for production rules that describe the mesh design strategy. An object- oriented inference engine is utilized to apply this rule set to the knowledge base where the symbolic representation of the structural configuration is stored.
