• 中文摘要： 本文將微分模式之基本?念推展於複合材料之熱彈性力學問題，藉以探求其有效熱彈係數。顆粒加強複合材料之力學性 質更為研究旨趣所在，其中加?顆粒之形狀除?圓球狀外，亦考慮針狀、盤狀情形。由分析結果知盤狀加?顆粒對複合材料 性質之影響最?顯著。此外，微分模式所得之結果不違反已知之熱彈係數上下限，與其他模式相較，,則更?優良合理。
• 英文摘要： The basic idea of differential scheme is extended to include thermoelasticity of composites, and the effective thermoelastic moduli of composites are explored by this scheme in detail. Special attention is given to particulate composite in which homogeneous isotropic inclusions are embedded in a homogeneous isotropic matrix. Cases considered are those where the inclusions are of needle shape, disk shape as well as spherical shape. It is concluded that a matrix with disk-shaped inclusions has the most significant effect on the moduli of composite. The scheme is evaluated favorably in comparison with the self-consistent scheme and the Hashin-Shtrikman bounds.
