Estimation of frictional damping of bolted plate structures by dynamic contact analysis

open access: yesNihon Kikai Gakkai ronbunshu, 2021
In mechanical structures where the components are joined by bolts, the vibration damping depends mainly on energy dissipation due to friction at the contact surfaces.

Reflection and transmission at the boundary surface of modified couple stress thermoelastic media

open access: yesInternational Journal of Applied Mechanics and Engineering, 2016
In this paper the reflection and transmission at a plane interface in modified couple stress generalized thermoelastic solid half spaces in the context of Loard-Shulman (LS) and Green-Lindsay (GL) theories in welded contact are investigated.

S/P Amplitude Ratios Derived from Single-Component Seismograms and Their Potential Use in Constraining Focal Mechanisms for Microearthquake Sequences

open access: yesThe Seismic Record, 2022
Focal mechanisms, which reflect the sense of slip in earthquakes, provide important constraints for understanding crustal tectonics and earthquake source physics, including the interactions among earthquakes during mainshock–aftershock sequences or ...

Universal amplitude ratios in the two-dimensional Ising model [PDF]

open access: yes, 1998
We use the results of integrable field theory to determine the universal amplitude ratios in the two-dimensional Ising model. In particular, the exact values of the ratios involving amplitudes computed at nonzero magnetic field are provided.Comment: 9 ...

Amplitude ratios for complete moment tensor retrieval [PDF]

open access: yesGeophysical Research Letters, 2005
We generalized the Snoke's method of inversion of amplitude ratios and polarities (P, SH, SV) designed to determine double‐couple earthquake focal mechanism (Snoke, 2003). We search for a general dipole source described by unconstrained seismic moment tensor, i.e. non‐double‐couple (non‐DC) source components are allowed as well.

Study of Axi-Symmetric Vibrations in a Micropolar Transversely Isotropic Layer

open access: yesInternational Journal of Applied Mechanics and Engineering, 2019
The present investigation deals with the propagation of circular crested Lamb waves in a homogeneous micropolar transversely isotropic medium. Secular equations for symmetric and skew-symmetric modes of wave propagation in completely separate terms are ...

Universal Amplitude Ratios in the Ising Model in Three Dimensions [PDF]

open access: yes, 2011
We use a high-precision Monte Carlo simulation to determine the universal specific-heat amplitude ratio A+/A- in the three-dimensional Ising model via the impact angle \phi of complex temperature zeros.

Reflection phenomena of waves through rotating elastic medium with micro-temperature effect

open access: yesReviews on Advanced Materials Science, 2020
In this article, we analyzed the effect of variable thermal conductivity on reflected elastic waves. The waves are propagating through a thermoelastic medium rotating with some angular frequency.

Surface wave characteristics in a micropolar transversely isotropic halfspace underlying an inviscid liquid layer

open access: yesInternational Journal of Applied Mechanics and Engineering, 2014
The present investigation deals with the propagation of waves in a micropolar transversely isotropic half space with an overlying inviscid fluid layer. Effects of fluid loading and anisotropy on the phase velocity, attenuation coefficient, specific loss ...
