摘要
采用随机域外奇点法对轴拉杆件进行了分析 .考虑杨氏模量的不确定性 ,得到了不同相关类型、不同相关长度下的解析解 ,并分析了相关类型、相关长度以及随机场中点离散法对位移方差的影响 .
The stochastic analysis of axially-loaded bars by singular points outside domain method is presented, in which the uncertainty of Young’s modulus is taken into consideration. Analytical solutions corresponding to different covariance structures and fluctuation scales are obtained. Based on this, the effects on the stochastic results of covariance structures, fluctuation scales and mid-point discretization of random field are given.
