Application of stochastic element-free point interpolation .method based on perturbation technique to structural reliability analysis
摘要
Abstract
To effectively solve the coefficient matrix singularity problems and calculation accuracy problem in the field of stochastic structure calculation with point interpolation method, the radial basis function (RBF) with polynomial and stochastic perturbation technique is applied to stochastic structural reliability analysis. Using RBF coupling polynomial primary function,the interpolation function has the properties of Kronecker Delta function, easily exerting the essential boundary conditions. Numerical examples show that this method not only has higher calculation accuracy but also improves the computational efficiency in the stochastic structure field.关键词
