Abstract

This paper assesses thermoelastic damping (TED) in circular nanoplates by incorporation of the small-scale effect into structural and thermal domains. The nonlocal elasticity theory and dual-phase-lag (DPL) heat conduction model are exploited for achieving the size-dependent coupled thermoelastic equations. By choosing time-harmonic and asymmetric form for deflection and temperature change, and solving the size-dependent thermoelastic eigenvalue problem, the damped natural frequency of circular nanoplate is extracted. On the basis of the complex frequency approach, an analytical relation, for the description of TED in circular nanoplates, is derived. For different boundary conditions and vibration modes, a comparison study is performed between the size-dependent results and those provided by classical continuum mechanics and heat conduction theories. Outcomes show a discrepancy between results acquired by the size effect on the structure and heat conduction. It is elucidated that how nonlocal and DPL characteristic parameters can represent the size-dependent phenomenon and can affect the magnitude of TED. A comprehensive parametric study is conducted to specify the influence of boundary constraints, vibration mode and the type of material on the amount of energy loss from TED. [ABSTRACT FROM AUTHOR]

Abstract

The disc cutter is used in the excavation of hard rock as one of the driving parts, so it is necessary to study the variation and distribution of thermal stress caused by contact friction with rock during the excavation. In this paper, the numerical simulation analysis of the rock breaking process of the disc cutter was carried out by using the software Abaqus and the dynamic simulation and mechanical analyses. The simulation results show the thermal stress distribution law very well. With the help of three-dimensional model of the cutter ring and rock, thermal, mechanical and coupling stress analyses on the effectiveness of rock breakage were carried out based on friction characteristics and the influence of relevant tool parameters. The results of this study will be helpful to study the thermal stress field distribution of Tunnel Boring Machine (TBM) disc cutter and maximise the tunnelling benefit.
