The self-excitation damping ratio: A chatter criterion for time-domain milling simulations [PDF]

, 2004
Regenerative chatter is known to be a key factor that limits the productivity of high speed machining. Consequently, a great deal of research has focused on developing predictive models of milling dynamics, to aid engineers involved in both research and ...

Blade dynamic stress analysis of rotating bladed disks [PDF]

Applied and Computational Mechanics, 2007
The paper deals with mathematical modelling of steady forced bladed disk vibrations and with dynamic stress calculation of the blades. The blades are considered as 1D kontinuum elastic coupled with three-dimensional elastic disk centrally clamped into ...

$O(N)$ fluctuations and lattice distortions in 1-dimensional systems [PDF]

, 2018
Statistical mechanics harmonizes mechanical and thermodynamical quantities, via the notion of local thermodynamic equilibrium (LTE). In absence of external drivings, LTE becomes equilibrium tout court, and states are characterized by several ...

Vibrational Heat Transfer Intensification in an Annulus with a Deformable Boundary

Shock and Vibration, 2019
An experimental study is carried out on heat transfer in a horizontal liquid annulus at boundary oscillations. The inner boundary is formed by a copper rod that is heated using electric current.

Excitation of vibrational soft modes in disordered systems using active oscillation [PDF]

, 2016
We propose a new method to characterize the spatial distribution of particles' vibrations in solids with much lower computational costs compared to the usual normal mode analysis.

Nonlinear vibrations of a moving rail-vehicle excited by snaking and lateral impacts of wheel sets

Computer Assisted Methods in Engineering and Science, 2022
The paper develops a theory of physically non-linear vibrations of a rail-vehicle moving on a rectilinear and non-deformable track. The vibrations are excited by snaking and lateral impacts of the wheel sets.

Vibrations of Cylindrical Shell Structures Filled With Layered Viscoelastic Material [PDF]

E3S Web of Conferences, 2021
A thin-walled shell and a thick-walled mass (cylinder) in contact with it, made of a different material, are structural elements of many machines, apparatus, and structures.

On the use of the theory of dynamical systems for transient problems

, 2013
This paper is a preliminary work to address the problem of dynamical systems with parameters varying in time. An idea to predict their behaviour is proposed.

Nonconservative dynamics in long atomic wires [PDF]

, 2014
The effect of nonconservative current-induced forces on the ions in a defect-free metallic nanowire is investigated using both steady-state calculations and dynamical simulations.

Potential method in the theory of Moore-Gibson-Thompson thermoporoelasticity

Archives of Mechanics
In the present paper the linear theory of Moore–Gibson–Thompson thermoporoelasticity is considered and the basic boundary value problems (BVPs) of steady vibrations are investigated.
