The incremental method has been widely used in various types of nonlinear analysis, however, so far it received little attention the analysis periodic vibrations. In this paper, an amplitude variational principle for vibrations elastic systems is derived. Based on approximate procedures can be adapted to formulation. linear solution system as starting point procedure and then increased incrementally. Within each step, only a set equations solved obtain data next stage. To show effectiveness...

A variable parameter incrementation method is proposed and then applied to the determination of parametric instability boundary columns. Attention particularly paid geometrically nonlinear problems including vibrations. Although only beam column are treated at present, approach believed be general in methodology. This not subjected limitations small exciting parameters weak nonlinearity.
Abstract The humidity sensor is an essential sensing node in medical diagnosis and industrial processing control. To date, most of the reported relative sensors have a long response time several seconds or even hundreds seconds, which would limit their real application for certain critical areas with fast-varying signals. In this paper, we propose flexible low-cost using vertically aligned carbon nanotubes (VACNTs) as electrodes, PDMS-Parylene C double layer substrate, graphene oxide...
Abstract Curved displays can adjust their shape to accommodate different objects and are used in electronics decorative lighting. Due the immutable pixel spacing, existing commercial curved flexible but not compatible with undevelopable surfaces. Inspired by kirigami auxetic structures, we propose an approach that combines luminescent elements rotating square tessellations create a stretchable, arbitrary curve adaptive display. We connect islands vertical interconnects relieve stress...
An incremental harmonic balance method with multiple time scales is presented in this paper. As a general and systematic computer method, it capable of treating aperiodic “steady-state” vibrations such as combination resonance, etc. Moreover, not subjected to the limitation weak nonlinearity. To show essential features new approach, almost periodic free vibration clamped-hinged beam computed an example.
Abstract Based on an incremental Hamilton's principle a versatile and systematic computer method for analysing non‐linear structural vibrations is developed in this paper. The essence of the proposed can be regarded as harmonic balance associated with finite strip procedure time‐space domain. Only linearized equations terms frequency increment, amplitude increments, etc. have to formulated solved each step. This applicable highly problems may generalized related periodic motions such dynamic...
Synopsis Plates and beams on elastic continuum are analysed using the finite element method. The horizontal contact pressures at interface between structure foundations have been incorporated in analysis effects due to separation of surfaces uplift also investigated. Des plaques et des poutres sur un milieu continu élastique sont analysées en utilisant la méthode à élément fini. Les pressions de l'interface entre les fondations ont été incorporées dans l'analyse effets dûs séparation dûe...
Stretchable and curved electronic devices are a promising technology trend due to their remarkable advantages. Many approaches have been developed manufacture stretchable electronics. Here, allow such electronics better serve practical applications, ranging from wearable soft robotics, we propose novel vertical serpentine conductor (VSC) with superior electrical stability interconnect functional through silicon-based microfabrication process. Conformal vacuum transfer printing (CVTP) was the...
