Due to an unfortunate turn of events, Eqs. 52, 155, 156 and 157 contain errors. Please find below the correct version of the equations mentioned that should be regarded as the final version by the reader.
Time-varying mesh stiffness (TVMS) is an important excitation source of a planetary gear set. Sliding friction and spalling defects have significant effect on the TVMS. Accurate evaluation of the TVMS can help obtain the vibration characteristics …
The linear stability of a heat-exchanger tube modeled as a single-span cantilever beam subjected to cross-flow has been studied with two parameters: (1) varying stiffness of the baffle-cladding at the free end and (2) varying flow velocity. A …

This paper presents an analytical method to investigate the dissimilar piezoelectric materials containing periodic cracks in the presence of uniform electromechanical loads with consideration of the Maxwell stress. Using Stroh’s formalism and …
This study focuses on vibration characteristics analysis of fiber metal laminated thin plate (FMLTP) with partial constraint layer damping (CLD) patches treatment. Firstly, the overall stress–strain relationships of the viscoelastic layer, the …
Secondary shape optimization for topological boundary is proposed to further improve heat dissipation performance of cold plates. Firstly, the topological boundaries obtained with topology optimization are fitted parametrically by Bezier curves.
The stability of a cylindrical interface separating two incompressible, inviscid and immiscible fluids under the action of radial motion is studied. Linear stability analysis is employed to understand the destabilization characteristics of the two …
Landing gear shimmy is a self excited vibration phenomenon which must be avoided during aircraft design due to its potentially catastrophic behaviour. In a preliminary specification of structural properties of a landing gear, if shimmy is verified …
