摘要: 采用彈性力學、復合材料力學以及計算數學的有關理論,建立起了軸對稱功能梯度材料分析模型,結合這類材料實際應用背景,給出了理論模型求解的邊界條件。在求解梯度層層間熱應力的過程中,引入了三角級數來描述功能梯度材料層間熱應力,從而得到了層間熱應力的精確解,以此優化這類材料的設計與實現該類材料的成功制備。Abstract: Analytical model for axial symmetrical functionally graded materials(FGM) is established based on the elasticity theory and computational mathematical model. The boundary conditions of the model is determined according to its application background. Triangle series are employed to describe the thermal stress caused by the difference of thermal expansion coefficients. Thus the accurate stress distribution has been calculated.
