给出了轴对称机械载荷和热载荷作用下功能梯度旋转厚壁圆管的热弹性解。我们假设管子由两个线弹性成分组成，其中一个相的体积分数是沿径向变化的幂函数。采用均匀应变场的假设，给出了位移和应力的理论解。该方法基于细观力学中各组分的体积平均应力与复合材料宏观应力的关系，避免了已有文献中出现的杨氏模数、热膨胀系数、导热系数、密度等未知材料总体参数分布规律的假设。系统地研究了角速度、体积分数、两个热膨胀系数之比、两个导热系数之比以及两个密度之比对位移和应力的影响，这将有助于结构工程师和材料科学家优化设计含有非均匀材料的厚壁圆筒。
A thermoelastic solution for the functionally graded rotating thick-walled tube subjected to axisymmetric mechanical and thermal loads is given in terms of volume fractions of constituents. We assume that the tube consists of two linear elastic constituents and the volume fraction of one phase is a power function varied in the radial direction. By using the assumption of a uniform strain field within the representative volume element, the theoretical solutions of the displacement and the stresses are presented. Based on the relation of the volume average stresses of constituents and the macroscopic stresses of the composite material in micromechanics, the present method can avoid the assumption of the distribution regularities of unknown overall material parameters appeared in existing papers, such as Young’s modulus, thermal expansion coefficient, thermal conductivity, and density. The effects of the angular velocity, the volume fraction, the ratio of two thermal expansion coefficients, the ratio of two thermal conductivities, and the ratio of two densities on the displacement and stresses are systematically studied, which should help structural engineers and material scientists optimally design thick-walled tube comprised inhomogeneous materials.
