Abstract: In this research we study the dynamics of a coupled linear oscillatorbistable energy harvester system. The method of harmonic balance and perturbation analysis are used to predict the existence and stability of the bistable ...

Abstract: The excitationinduced stability (EIS) phenomenon in a harmonically excited bistable Duffing oscillator is studied in this paper. Criteria to predict system and excitation conditions necessary to maintain EIS are derived ...

Abstract: Recent studies on periodic metamaterial systems have shown that remarkable properties adaptivity and versatility are often the products of exploiting internal, coexisting metastable states. Motivated by this concept, this ...

Abstract: Reflecting on the application and implications of this work [1], the authors realized that a few items should be discussed.Although the work is for elastic sliding contact, it could be adapted for elastic–plastic contact ...

Abstract: A numerical simulation of forced convective condensation of propane in an upright spiral tube is presented. In the numerical simulations, the important models are used: implicit volume of fluid (VOF) multiphase model, ...

Abstract: In order to investigate the impact of fault on the stability of the water-resisting layer of the coal floor, the critical water pressure formula of the water-resisting layer failure under the influence of fault is deduced ...
