The present contribution enlightens the analysis of thermoelastic vibrations of a nano-beam subjected to a variable axial load. Both ends of the beam are considered to be clamped. In contrast to the previous studies where the initial axial load is assumed to be constant, the present study ...

摘要: In this paper, the transition from a 3-D thermoelasticity problem to a 1-D beam model is made on the basis of a two-scale asymptotic method. A non-homogeneous beam of arbitrary periodic structure is considered.DOI: 10.1016/S0020-7225(98)00066-4 被引量: 12 ...
A Size-Dependent Generalized Thermoelasticity Theory for Thermoelastic Damping in Vibrations of Nanobeam Resonators Thermoelastic damping (TED) has been discerned as a definite source of intrinsic energy loss in miniaturized mechanical elements. The size-dependent struct... JA Turki,SZ Muter,IA Falah,....
We present two versions of a mathematical model for the evolution of wear in a thermoelastic beam resulting from frictional contact with a rigid moving surface. One version is quasistatic and the other dynamic. We show that the quasistatic problem allows for the decoupling of the mechanical and...
We consider the steady case of a nonlinear model for a thermoelastic beam that can enter in contact with obstacles. We rst prove the well-posedness of this problem. Next, we propose a nite element discretization and perform the a priori and a posteriori analysis of the discrete problem. Some...

In this paper, the effect of thermoelastic coupling on a micro-machined resonator is studied. The calculated results show that the frequency shift ratio caused by thermoelastic coupling is of the order of 10−3, which is much larger than that of air-damping. Furthermore, the non-dimensional...
