نویسندگان
چکیده
In this paper, the Lyapunov exponent and moment exponents of two degrees-of-freedom linear systems subjected to white noise parametric excitation are investigated. The method regular perturbation is used determine explicit asymptotic expressions for these in presence small intensity noises. important characteristics determining both almost-sure stability a stochastic dynamic system. As an example, we study thin-walled beam axial load stochastically fluctuating end moments. validity approximate results checked by numerical Monte Carlo simulation

رابطه ی میانِ هنر و شرایطِ اجتماعیِ زایش آن همواره در طولِ تاریخ دغدغه ی ذهنی و دل مشغولیِ اساسیِ منتقدان و نیز هنرمندان بوده است. از آنجا که هنر در قفس آهنیِ زندگیِ اجتماعی محبوس است، گسترش وابستگیِ آن با نهاد ها و اصولِ اجتماعی پیرامون، صرفِ نظر از هم سو بودن و یا غیرِ هم سو بودنِ آن نهاد ها، امری اجتناب ناپذیر به نظر می رسد. با این وجود پدیدار گشتنِ چنین مباحثِ حائز اهمییتی در میان منتقدین، با ظهورِ مکتب ما...
Dynamic Instability Analysis of Embedded Multi-walled Carbon Nanotubes under Combined Static and Periodic Axial Loads using Floquet–Lyapunov Theory
The dynamic instability of single-walled carbon nanotubes (SWCNT), double-walled carbon nanotubes (DWCNT) and triple-walled carbon nanotubes (TWCNT) embedded in an elastic medium under combined static and periodic axial loads are investigated using Floquet–Lyapunov theory. An elastic multiple-beam model is utilized where the nested slender nanotubes are coupled with each other through the van d...
متن کاملA Survey on Buckling and Vibrations of a Viscoelastic Beam under Distributed Lateral and Axial Loads
In this paper, based on Kelvin and Linear Standard Solid models, dynamic response and the buckling load of a viscoelastic beam under lateral and axial loads have been determined. The governing equations have been extracted using Euler and Timoshenko theories and their analytical solutions have been obtained by using the eigenfunctions expansion method. Buckling load have been calculated by us...
