TL;DR: In this paper, the problem of response surface modeling of limit surface lying within two hyper spheres of prescribed radii is considered, and the relevance of this problem in structural reliability analysis involving performance functions with multiple design points and/or multiple regions that make significant contributions to failure probability is discussed.

TL;DR: In this article, the authors exploit the dynamics of a base excited double pendulum to generate electricity in small scale, where the mass of the pendulum is assumed to be concentrated at the bobs.

TL;DR: In this article, the aeroelastic response of a NACA 0012 airfoil in the flow regimes prior to flutter is investigated in a wind tunnel, where the authors observe intermittent bursts of periodic oscillations in the pitch and plunge response, that appear in an irregular manner from a background of relatively lower amplitude aperiodic fluctuations.

TL;DR: In this paper, the authors considered the problem of reliability analysis of randomly driven, stochastically parametered, vibrating structures, where the excitation components were assumed to be jointly stationary, Gaussian random processes.

TL;DR: In this paper, the stochastic bifurcations in a vibro-impact Duffing-Van der Pol oscillator, subjected to white noise excitations, are investigated.
