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......
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......
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......
Rigorous constructive solution to monodimensional poiseuille and thermal creep flows
Meccanica - Tập 11 - Trang 183-190 - 1976
A rigorous constructive method is discussed for solving the linear integral equations which govern either the Poiseuille flow and the thermal creep flow of a rarefied gas between parallel plates. In both cases numerical results are presented for the nondimensionalized mass flow rate, and for certain quantities which are closely related to the mass and slip velocities. Critical comparison with prev......
The limit state of indefinite plates on elastoplastic continuum
Meccanica - Tập 7 - Trang 117-123 - 1972
The limit analysis of indefinite plates resting on a continuous elastoplastic medium and subjected to a load distributed over a partial surface with a circular boundary yields the fundamental equation governing the problem. Minimum conditions are set and the solution that supplies the collapse load of the plate-soil system is found by variational calculus.
Inertial and self interactions in structured continua: Liquid crystals and magnetostrictive solids
Meccanica - Tập 30 - Trang 629-640 - 1995
Evolution equations for liquid crystals and for magnetostrictive solids are discussed within the framework of a theory of continua with microstructure that allows for mechanical self-interactions and non-standard inertial terms.
