Effect of rotation on plane waves in generalized thermo-microstretch elastic solid with a relaxation time
Meccanica - Tập 47 - Trang 1467-1486 - 2012
The present paper is aimed at studying the effect of rotation on the general model of the equations of generalized thermo-microstretch for a homogeneous isotropic elastic half-space solid whose surface is subjected to a Mode-I Crack problem considered. The problem is in the context of the generalized thermoelasticity Lord-Şhulman’s (L-S) theory with one relaxation time, as well as the classical dy......
The membranal and flexural equations of thin elastic plates deduced exactly from the three-dimensional theory
Meccanica - Tập 24 - Trang 93-97 - 1989
The classical field and boundary equations governing the in-plane stretching and the transversal bending of a thin plate are obtained by means of an exact mathematical procedure consisting in integrating over the thickness the equilibrium equations for a three-dimensional cylindrical body, made of a homogeneous, linearly elastic, transversely isotropic material, and subject to suitable internal co......
Design and experimental characterization of a high performance hydrostatic transmission for robot actuation
Meccanica - Tập 55 - Trang 1169-1179 - 2020
This paper introduces a hydrostatic torque-transmission for robotic applications based on rolling diaphragm cylinders. The proposed design solution, that relies on a novel floating-cylinder architecture, can be effectively employed for the implementation of robots with actuators that are remotely located with respect to their kinematic structure, without sacrificing performance and controllability......
A discontinuous Galerkin method for non-linear electro-thermo-mechanical problems: application to shape memory composite materials
Meccanica - Tập 53 - Trang 1357-1401 - 2017
A coupled electro-thermo-mechanical discontinuous Galerkin (DG) method is developed considering the non-linear interactions of electrical, thermal, and mechanical fields. In order to develop a stable discontinuous Galerkin formulation the governing equations are expressed in terms of energetically conjugated fields gradients and fluxes. Moreover, the DG method is formulated in finite deformations ......
Nonlinear dynamic analysis for coupled vehicle-bridge system with harmonic excitation
Meccanica - Tập 52 - Trang 2219-2243 - 2016
In this paper, a multi-degree-of-freedom lumped parameter coupled vehicle-bridge dynamic model is proposed considering the nonlinearities of suspension and tire stiffness/damping and the nonlinear foundation of bridge. In terms of modelling, the continuous expressions of the kinetic energy, potential energy and the dissipation function are constructed. The dynamic equations of the coupled vehicle-......
Reciprocal gausson phenomena in a Korteweg capillarity system
Meccanica - Tập 54 - Trang 1515-1523 - 2019
In previous work in the literature, a kinetic derivation of a logarithmic nonlinear Schrödinger equation incorporating a de Broglie–Bohm term has been obtained in a capillarity context. Here, gausson-type solutions are constructed for such an NLS model. A novel two-parameter class of reciprocal transformations is shown to leave the 1 + 1-dimensional Korteweg capillarity system invariant and is app......
Investigation of the Dynamic Behavior of a Griffith Crack in a Piezoelectric Material Strip Subjected to the Harmonic Elastic Anti-plane Shear Waves by Use of the Non-local Theory
Meccanica - Tập 39 - Trang 63-76 - 2004
In this paper, the dynamic behavior of a Griffith crack in a piezoelectric material strip subjected to the harmonic anti-plane shear waves is investigated by use of the non-local theory for impermeable crack surface conditions. To overcome the mathematical difficulties, a one-dimensional non-local kernel is used instead of a two-dimensional one for the anti-plane dynamic problem to obtain the stre......
