Perturbation stochastic Cell-Based smoothed finite element method for laminated composite plates
摘要
Abstract
The randomness is the inherent characteristics of the practical engineering structures ,and it has great practical significance for the reliability design of the engineering structures to describe the random response and statistics of response of the structures with random parameters truly .The smoothed finite element formulations of laminated composite plates based on the first-order shear deformation theory were derived adopting quadrilateral element the based on Cell-Based smoothed finite element ,and the de-mand of the mesh generation was decreased so that the elements are allowed to be of arbitrary shapes , the shear locking was eliminated by using discrete shear gap .The equilibrium equation of the perturba-tion random smoothed finite element and the numerical characteristics of structural random responses were derived by combining the perturbation method and random field theory .The random responses of the laminated composite plates with the random material properties were solved ,and the numerical re-sults indicate that the approach proposed is correct and feasible .关键词
