Abstract

IN THE PRESENT STUDY, AN ANALYTICAL CLOSED FORM SOLUTION FOR FREE VIBRATION RESPONSE OF HYBRID COMPOSITE PLATE REINFORCED WITH SHAPE MEMORY ALLOY (SMA) FIBERS IS DERIVED. RECOVERY STRESSES GENERATED DURING MARTENSITIC PHASE TRANSFORMATION ARE OBTAINED BASED ON ONE-DIMENSIONAL BRINSONÂS MODEL. THE MECHANICAL PROPERTIES OF PLATE ARE ASSUMED TO BE TEMPERATURE DEPENDENT. BASED ON THE FIRST-ORDER SHEAR DEFORMATION THEORY (FSDT) THE GOVERNING EQUATIONS ARE OBTAINED VIA HAMILTONÂS PRINCIPLE. RITZ METHOD IS USED TO OBTAIN THE FUNDAMENTAL NATURAL FREQUENCY OF THE PLATE FOR DIFFERENT TEMPERATURES. A DETAILED PARAMETRIC ANALYSIS SHOWS THE STRONG INFLUENCE OF THE VOLUME FRACTION, PRE-STRAIN, ORIENTATION AND LOCATION OF SMA FIBERS AS WELL AS THE ASPECT RATIO OF THE PLATE ON THE FUNDAMENTAL NATURAL FREQUENCY AND THE ONSET OF THE THERMAL BUCKLING.
