Statistical Moments of Polynomial Dimensional Decomposition
Publication: Journal of Engineering Mechanics
Volume 136, Issue 7
Abstract
This technical note presents explicit formulas for calculating the response moments of stochastic systems by polynomial dimensional decomposition entailing independent random input with arbitrary probability measures. The numerical results indicate that the formulas provide accurate, convergent, and computationally efficient estimates of the second-moment properties.
