Abstract : In recent years, techniques of 'heuristic programming' have been applied to various fields of science and engineering. An attempt has been made, during the current investigation, to develop a knowledge based consultation system and to establish a finite element structural analysis knowledge based for the use of the MARC program, a general purpose finite element analysis program. Backward chaining logic is adopted into the current system and the inference engine is written in Fortran. The knowledge based deals with information on pre-analysis, and post-analysis stages of a structural analysis problem. Rules in the knowledge base are executed through the use of user input keywords. The consultation system is currently operational on the Prime 400 Computer System. (Author)
