Abstract: Drill bit vibrations are modeled using the Euler-Bernoulli beam theory. The model includes the most important properties of drill bits and of the drilling operation. These are: the drill bit ...

Abstract: Finite element solutions are used to analyze the effects of geometric and process parameters on the drill bit transverse vibrations. The effects of cross sectional geometry, of the flute helix ...

Abstract: This study is concerned with the free bending vibrations of two rectangular, orthotropic plates connected by an adhesively bonded lap joint. The influence of shear deformation and rotatory inertia ...
