Stochastic thermal buckling analysis of laminated plates using perturbation technique

Composite Structures, 2016
Abstract Composites are known to display a considerable amount of scatter in their material properties due to large number of parameters involved with the manufacturing and fabrication processes. This paper is concerned with the effect of random system properties on critical thermal buckling temperature of composite laminated plates with temperature ...

Random Eigenvibrations of Elastic Structures by the Response Function Method and the Generalized Stochastic Perturbation Technique

Archives of Civil and Mechanical Engineering, 2009
This paper addresses the important question in structural analysis how to efficiently model the eigenvibrations of the spatial structures with random physical and/or geometrical parameters. The entire computational methodology is based on the traditional Finite Element Method enriched with the stochastic perturbation technique in its generalized nth ...

Optimization of a smooth flat plate solar air heater using stochastic iterative perturbation technique

Solar Energy, 2011
Abstract Due to low heat transfer capability, the thermal efficiency of solar collectors is very low and various techniques are implemented to increase the performance of solar air heaters. There is a need for optimization of design and operating parameters for maximizing the thermal gain from the solar air heating systems. In this paper a stochastic

Response Probability Analysis of Random Acoustic Field Based on Perturbation Stochastic Method and Change-of-Variable Technique

Journal of Vibration and Acoustics, Transactions of the ASME, 2013
To calculate the probability density function of the response of a random acoustic field, a change-of-variable perturbation stochastic finite element method (CVPSFEM), which integrates the perturbation stochastic finite element method (PSFEM) and the change-of-variable technique in a unified form, is proposed.

Simple analytical solution for multiplicative nonlinear stochastic differential equations by a perturbation technique

Physical Review A, 1986
A simple convergent and analytical solution valid for the whole time range for the stochastic Verhulst equation is obtained by treating the strength of the external Gaussian white noise as a perturbation without using the existing approach where the moments are expressed by means of an integral representation.

The stochastic second-order perturbation technique in the finite difference method

Communications in Numerical Methods in Engineering, 2001
AbstractThe main idea of the paper is to introduce the second‐order perturbation second probabilistic moment extension of the finite difference method (FDM). The approach can be successfully applied to all these engineering analyses where FDM modelling is still useful and some structural parameters are treated as random variables or fields.
