Stochastic multi-scale finite element analysis for laminated composite plates

International Conference on Applications of Statistics and Probability (12th : 2015 : Vancouver, B.C.)

This paper proposes a dual stochastic finite element method for conducting stochastic analysis for laminated composite plates with consideration of microscopic material property uncertainties. A stochastic multiscale finite element method, which couples the multiscale computation homogenization method with the second order perturbation technique, is developed first to propagate variability in the effective elasticity property of composite arising from microscopic uncertainties such as Young’s modulus and Poisson’s ratio of constituent materials. Then a standard stochastic finite element analysis is conducted to consider structural level uncertainties. The performance of the proposed approach is evaluated by comparing the estimates of mean values and coefficients of variation for the effective elastic properties and structural response for a laminated composite plate with corresponding results from the Monte Carlo simulation method.
