本文研究了含功能梯度材料夹层的复合材料层合厚板在宽度方向上不均匀加热时的瞬态热应力问题。假设功能梯度材料中间层的热常数和热弹性常数沿厚度方向呈指数变化。本文给出了平面应变状态下简支带二维瞬态温度场和热应力场的精确解。温度变化、位移和应力分布的一些数值结果如图所示。此外，还研究了中间层的厚度和位置的影响。
This paper is concerned with the theoretical treatment of transient thermal stress problem involving a laminated composite thick strip with an interlayer of functionally graded material due to nonuniform heat supply in the width direction. The thermal and thermoelastic constants of the interlayer of functionally graded material are assumed to vary exponentially in the thickness direction. We obtain the exact solution for the two-dimensional temperature change in a transient state, and thermal stresses of a simple supported strip under the state of plane strain. Some numerical results for the temperature change, the displacement and the stress distributions are shown in figures. Furthermore, the influence of the thickness and position of the interlayer is investigated.
