Bifurcation of elastoplastic pressure-sensitive spheres
Instability of a full sphere, under uniform compression or tension, is investigated within the framework of linear bifurcation theory. Material response is modeled by a Hookean-type hypoelastic relation with pressure dependent instantaneous moduli. Exploiting a formal analogy with Navier equations of linear elasticity we obtain exact solution for the bifurcated field. Two families of eigenmodes...
متن کاملStrain-rate-dependent model for the dynamic compression of elastoplastic spheres.
We present a force-displacement contact model for the compressive loading of elastoplastic spheres. This model builds from the well known Hertz contact law for elastic, quasistatic compression to incorporate a material's strain-rate-dependent plasticity in order to describe collisions between particles. In the quasistatic regime, finite-element analysis is used to derive an empirical function o...
متن کاملA highly sensitive, low-cost, wearable pressure sensor based on conductive hydrogel spheres.
Wearable pressure sensing solutions have promising future for practical applications in health monitoring and human/machine interfaces. Here, a highly sensitive, low-cost, wearable pressure sensor based on conductive single-walled carbon nanotube (SWCNT)/alginate hydrogel spheres is reported. Conductive and piezoresistive spheres are embedded between conductive electrodes (indium tin oxide-coat...
متن کاملA pressure sensitive palatography: application of new pressure sensitive sheet for measuring tongue-palatal contact pressure
This paper describes a new method for measuring the tonguepalatal contact pressure using a thin pressure sensor and its application for speech research. The new pressure sensor is composed of thin pressure sensitive ink whose electrical resistance is proportional to the physical forces applied to the sensor. Several sensors were arranged on the surface of the palatal plate. This setup was used ...
متن کاملBifurcation of Vortices in the Light-Sensitive Oscillatory BZ Medium
We carried out experiments to study the e ect of local disturbances on the vortex dynamics in the light-sensitive Belousov Zhabotinsky (BZ) reaction. It was found that irradiation with visible light of the core region of a rotating spiral wave (vortex) in an oscillatory medium results in a bifurcation which dramatically changes the shape of the vortex. The bifurcation is seen as an unfolding in...
