Abstract

IN THIS PAPER, A NEW 12-NODE TRIANGULAR ELEMENT IS DEVELOPED FOR THE ANALYSIS OF COMPOSITE PLATES. MOREOVER, THE STRESS-STRAIN RELATIONS OF LAMINATED BENDING PLATES, ALONG WITH THE CHARACTERISTICS OF COMPOSITE AND PIEZOELECTRIC MATERIALS HAVE ALSO BEEN INVESTIGATED. FOLLOWING THIS, A FINITE ELEMENT FORMULATION FOR SMART COMPOSITE BENDING PLATES IS PROPOSED. THE CAPABILITY OF THE SUGGESTED ELEMENT IN ANALYZING BOTH COMPOSITE PLATES AND SMART ONES IS STUDIED VIA NUMERICAL EXAMPLES. THESE ANALYSES DEMONSTRATE THAT THE PROPOSED ELEMENT IS CAPABLE OF YIELDING ACCURATE RESULTS FOR THE GIVEN PROBLEMS. IN ADDITION, IT IS ALSO CONCLUDED THAT IN COMPARISON TO THE ELEMENTS DEVELOPED BY OTHER RESEARCHERS, THIS NEW FORMULATION LEADS TO MORE PRECISE OUTCOMES.
