功能梯度材料圆筒的定常温度分布及热应力

Steady State Temperature Distribution and Thermal Stress of Functionally Gradient Material Cylinder

利用线性热弹性理论研究了功能梯度材料圆筒的定常温度分布及热应力，在考虑各材料常数也存在梯度分布的条件下。

This paper discusses steady state temperature distribution and thermal stress of func tionally gradient material cylinder by using theory of linear thermoelasticity.On condition that material parameters present gradient distribution.The paper obtains a group of formulas for calculating temperature distribution and thermal stress.
