This paper proposes a new strategy based on the proper generalized decomposition method to solve forced vibration problem for bi-dimensional piezoelectric composite beams. The approach considers classical harmonic space-frequency description of dynamic and redefines it by approximating displacement electric potential fields as sum separated functions x (beam axis coordinate), z (thickness coord...

Computational analysis of free and forced vibration responses provides crucial information on the dynamic characteristics deformable bodies. Although such numerical techniques are prevalently used in many disciplines, they have been underutilized quest to understand form function human fingers. We addressed this opportunity by building DigiTip, a detailed three-dimensional finite element model ...

Abstract Dynamics of suspended cables with active vibration control is studied. The device an electrical absorber that driven by a motor and may be fixed at any position along the cable. applies force reduces amplitude where it placed. methodology efficient for attenuating high-frequency, low-amplitude due to periodic excitation consider wind effect. dynamic behavior described mechanical model ...
