Abstract
METAL MATRIX COMPOSITES (MMC) APPEAR VERY PROMISING FOR USE IN THERMALLY STABLE SATELLITE STRUCTURES. HIGH SPECIFIC MODULI AND LOW THERMAL EXPANSION APPEAR TO MAKE THESE MATERIALS IDEAL FOR SATELLITE APPLICATION. EXTREME THERMAL STABILITY REQUIREMENTS FOR SATELLITE SENSOR MOUNTING STRUCTURE REQUIRES THAT THE DESIGN OF SUCH STRUCTURE USING MMC TAKE INTO ACCOUNT THE NONLINEAR THERMOMECHANICAL RESPONSE EXHIBITED BY THESE MATERIALS. THIS EFFORT INVESTIGATES TWO CANDIDATE MECHANICAL MODELS FOR PREDICTING THE THERMO-MECHANICAL RESPONSE OF UNDIRECTIONAL MMC. THE INVESTIGATIONS FOCUS ON THE ABILITY OF THE TWO MODELS ACCURATELY TO PREDICT THE NO-LINEAR CONSTITUTIVE RELATIONS FOR MMC. A MODEL WILL BE RECOMMENDED FOR USE IN DEVELOPING AN INCREMENTAL LAMINATE ANALYSIS. THE CAPABILITY TO ANALYZE AND DESIGN MMC LAMINATES SUBJECTED TO THERMAL AND MECHANICALLOADING STATES IS A NECESSITY BEFORE MMC CAN BE FULLY UTILIZED IN SATELLITE STRUCTURES.
