점탄성-복합재 박판 블레이드 구조물의 진동 해석

다국어 초록 (Multilingual Abstract)

This paper concerns the analytical modeling and dynamic analysis of advanced cantilevered blade<br/>
structure implemented by a dual approach based on structural tailoring and viscoelastic materials technology.<br/>
Whereas structural tailoring uses the directionality properties of advanced composite materials, the passive<br/>
materials technology exploits the damping capabilities of viscoelastic material(VEM) embedded into the host<br/>
structure. The structure is modeled as a composite thin-walled beam incorporating a number of nonclassical<br/>
features such as transverse shear, secondary warping, anisotropy of constituent materials, and rotary inertias.<br/>
The case of VEM spreaded over the entire span of the structure is considered. The displayed numerical results<br/>
provide a comprehensive picture of the synergisitic implications of the application of both techniques, namely,<br/>
the tailoring and damping technology on vibration response of thin-walled beam structure exposed to external<br/>
time-dependent excitations.
