A Modeling approach for analysis and improvement of spindle-holder-tool assembly dynamics [PDF]
, 2006 The most important information required for chatter stability analysis is the dynamics of the involved structures, i.e. the frequency response functions (FRFs) which are usually determined experimentally.

Timoshenko Beam Effects in Lateral-mode Microcantilever-based Sensors in Liquids [PDF]
, 2013 Recent experimental and analytical research has shown that higher in-fluid quality factors (Q) are achieved by actuating microcantilevers in the lateral flexural mode, especially for microcantilevers having larger width-to-length ratios.

Vibration of Piezoelectric Nanowires Including Surface Effects [PDF]
Journal of Nanostructures, 2014 In this paper, surface and piezoelectric effects on the vibration behavior of nanowires (NWs) are investigated by using a Timoshenko beam model. The electric field equations and the governing equations of motion for the piezoelectric NWs are derived with
