Polynomial Chaos in Stochastic Finite Elements
Journal of Applied Mechanics, 1990A new method for the solution of problems involving material variability is proposed. The material property is modeled as a stochastic process. The method makes use of a convergent orthogonal expansion of the process. The solution process is viewed as an element in the Hilbert space of random functions, in which a sequence of projection operators is ...

Micromechanically based stochastic finite elements
Finite Elements in Analysis and Design, 1993Abstract A stochastic finite element method for analysis of effects of spatial variability of material properties is developed with the help of a micromechanics approach. The method is illustrated by evaluating the first and second moments of the global response of a membrane with microstructure of a spatially random inclusion-matrix composite under ...

Stochastic Finite Element Analysis of Composites
American Society for Composites 2018, 2018Composite materials can have a large variation in material properties, especially in the transverse direction. This can cause difficulty when designing with these materials and may lead to overdesigning the material. Using finite element software, a model was created to simulate failure of composite materials in the transverse direction.

Random fields and stochastic finite elements
Structural Safety, 1986Abstract This state of the art paper identifies as the distinguishing feature of stochastic finite element analysis that it involves the discretization of the parameter space of a random field of material properties and / or loads. This discretization implies that the stochastic input consists of a vector of random variables whose covariance matrix ...

Reliability Calculation of Stochastic Finite Element
2022The stochastic finite element third-order perturbation method for linear static problems is formulated. The stress-strength interference model, Monte Carlo simulation and a new iterative method (NIM) of reliability calculation for the linear static problem and linear vibration are proposed.

Stochastic Finite Element Analysis: an Introduction
2020With the aid of the finite element method, the present paper deals with the problem of structural response variability resulting from the spatial variability of material properties of structures, when they are subjected to static loads of a deterministic nature. Several forms of spatial variability of Young’s modulus and Poisson’s ratio are considered;
