A personal computer program of Finite Element Method was developed in the past in order to analyze the stresses in composite materials. Although the mechanical behavior of composite materials can be analyzed by such a developed computer program the compoent construction of laminates caIl no the obtained because it is very difficultto optimizet be computational results by using and dinar F E M on the other hand, theratio of layer components caIl be calculated by the method of optimization, but nottbelay-up Sequence of laminates. In this paper, the personal computer program of intelligent F E M With an ewconcepthas been developed in order to analyze the componentandlay-uP Sequence of laminates which satisfy thede- Sign objects・As an example of analysis, the material for each layer of alaminated pane lunderbend- ing condition was selected and the thickness of laminae under combined loads of bend in gadtension was determined. The computational results were very reasonable for the composite structure. There-1fore, it was recognized that the proposed intelligent F E M is very useful for the structure design of composite materials.
