含FGM的涂层结构中热残余应力的分析与优化

open access: yes, 2001
本文利用有限元方法和优化理论,对含FGM(Functionally Graded Materials)层的热喷涂构件中的残余应力进行了数值分析,并获得了FGM内各组份体积含量分布的最优化形式和参数p。同时,我们也研究了喷涂构件的几何形状、涂层及基底的材料性能对于p的影响规律。在本文的分析中,考虑了基底材料和FGM的塑性变形以及其性能对于温度的依赖 ...

Goodness‐of‐Fit Tests for Positive Quadrant Dependence

open access: yesInternational Statistical Review, EarlyView.
Summary When two random variables are positive quadrant dependent (PQD), they are more likely to assume small (or large) values simultaneously compared with when the random variables are independent. This dependence structure is of interest in many areas, including finance, actuarial science and engineering.
