On the Convergence of Stochastic Finite Elements [PDF]

open access: yes, 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 ...

Stochastic Finite Element for Structural Vibration [PDF]

open access: yesMathematical Problems in Engineering, 2010
This paper proposes a new method of calculating stochastic field. It is an improvement of the midpoint method of stochastic field. The vibration equation of a system is transformed to a static problem by using the Newmark method and the Taylor expansion is extended for the structural vibration analysis with uncertain factors.

Convergence of Finite Element Methods for Singular Stochastic Control [PDF]

open access: yesSIAM Journal on Control and Optimization, 2018
A numerical method is proposed for a class of stochastic control problems including singular behavior. This method solves an infinite-dimensional linear program equivalent to the stochastic control problem using a finite element type approximation, which results in a solvable finite-dimensional program.

Structural Uncertainty Analysis of High-Temperature Strain Gauge Based on Monte Carlo Stochastic Finite Element Method

open access: yesSensors, 2023
The high-temperature strain gauge is a sensor for strain measurement in high-temperature environments. The measurement results often have a certain divergence, so the uncertainty of the high-temperature strain gauge system is analyzed theoretically ...

A Stochastic Wavelet Finite Element Method for 1D and 2D Structures Analysis

open access: yesShock and Vibration, 2014
A stochastic finite element method based on B-spline wavelet on the interval (BSWI-SFEM) is presented for static analysis of 1D and 2D structures in this paper. Instead of conventional polynomial interpolation, the scaling functions of BSWI are employed

Deconvolution effect of near-fault earthquake ground motions on stochastic dynamic response of tunnel-soil deposit interaction systems [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2012
The deconvolution effect of the near-fault earthquake ground motions on the stochastic dynamic response of tunnel-soil deposit interaction systems are investigated by using the finite element method.

Solution of Static Field Problems With Random Domains [PDF]

open access: yes, 2010
A method to solve stochastic partial differential equations on random domains consists in using a one-to-one random mapping function which transforms the random domain into a deterministic domain.

Calculating the Malliavin derivative of some stochastic mechanics problems.

open access: yesPLoS ONE, 2017
The Malliavin calculus is an extension of the classical calculus of variations from deterministic functions to stochastic processes. In this paper we aim to show in a practical and didactic way how to calculate the Malliavin derivative, the derivative of
