New approach in Stochastic Finite Element Method [PDF]

open access: yesPAMM, 2004
AbstractIn the paper, the new methodology for Stochastic Finite Element Method (SFEM) as the means to analyze structure in the probabilistic framework is presented. The concept of random influence vector is introduced and used to develop the universal formulas in the framework of SFEM that can work effectively for a wide variety of random loads ...

Stochastic post-processing calculation of iron losses – application to a PMSM [PDF]

open access: yes, 2013
To take account of the uncertainties introduced on the magnetic properties during the manufacturing process, the present work aims to focus on the stochastic modelling of iron losses in electrical machine stators.

Spectral Stochastic Finite Element Method for Electromagnetic Problems with Random Geometry

open access: yesElectrical, Control and Communication Engineering, 2014
In electromagnetic problems, the problem geometry may not always be exactly known. One example of such a case is a rotating machine with random-wound windings.

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

Stochastic Finite Element Analysis of Plate Structures Considering Spatial Parameter Random Fields

open access: yesMathematics, 2023
For plate structures, their random parameters can be regarded as a two-dimensional random field in the plane. To solve the plate theory considering a two-dimensional random field, an efficient strategy for the stochastic finite element method was adopted.
