Stochastic finite elements: Where is the physics? [PDF]
Theoretical and Applied Mechanics, 2011 The micromechanics based on the Hill-Mandel condition indicates that the majority of stochastic finite element methods hinge on random field (RF) models of material properties (such as Hooke’s law) having no physical content, or even at odds with ...

Predicting the Probability of Failure of Cementitious Sewer Pipes Using Stochastic Finite Element Method. [PDF]
Int J Environ Res Public Health, 2015 In this paper, a stochastic finite element method (SFEM) is employed to investigate the probability of failure of cementitious buried sewer pipes subjected to combined effect of corrosion and stresses.

Conforming finite element methods for the clamped plate problem [PDF]
, 1975 Finite element methods for solving biharmonic boundary value problems are considered. The particular problem discussed is that of a clamped thin plate. This problem is reformulated in a weak, form in the Sobolev space Techniques for setting up conforming

Truncation Preconditioners for Stochastic Galerkin Finite Element Discretizations [PDF]
SIAM Journal on Scientific Computing, 2021 Stochastic Galerkin finite element method (SGFEM) provides an efficient alternative to traditional sampling methods for the numerical solution of linear elliptic partial differential equations with parametric or random inputs. However, computing stochastic Galerkin approximations for a given problem requires the solution of large coupled systems of ...

Iterative Solvers for the Stochastic Finite Element Method [PDF]
SIAM Journal on Scientific Computing, 2010 This paper presents an overview and comparison of iterative solvers for linear stochastic partial differential equations (PDEs). A stochastic Galerkin finite element discretization is applied to transform the PDE into a coupled set of deterministic PDEs.

Vehicle-bridge dynamic interaction using finite element modelling [PDF]
, 2010 First investigations on the dynamic response of bridges due to moving loads were motivated by the collapse of the Chester railway bridge in the UK in the middle of the 19th century.

THE STOCHASTIC FINITE ELEMENT METHOD FOR NUCLEAR APPLICATIONS [PDF]
Proceedings of the VII European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS Congress 2016), 2016 Nuclear materials are subjected to demanding environments, encountering high temperature gradients and fast neutron fluxes that gradually damage its structure and there-fore change the material properties. Some components of a nuclear reactor determine its life-time, such as the graphite core and steel pressure vessel for fission reactors.

On the Convergence of Stochastic Finite Elements [PDF]
, 2001 We investigate the rate of convergence of stochastic basis elements to the solution of a stochastic operator equation. As in deterministic finite elements, the solution may be approximately represented as the linear combination of basis elements. In the stochastic case, however, the solution belongs to a Hilbert space of functions defined on a cross ...
