【摘要】 针对梯度薄膜材料的特殊性,在平面应力近似基础上进行热弹性理论推导,结果表明,梯度薄膜材料的热应力极值由梯度薄膜材料本身的性质决定,组成分布系数只影响热应力的分布和变化趋势提出了梯度薄膜材料的设计原则. : u6 y! p7 n) d' [: ?' e
【英文摘要】 Aiming at the particularity of functionally gradient films and based on the plane stress hypothesis, the thermal elastic stress analysis for functionally gradient films has been carried out. It has been learned that limit of thermal stress is only determined by the thermomechanical properties of materials consisting of functionally gradient films and composition distribution coefficient films has been presented.
