Abstract

A powerful analytical procedure and strain energy analysis to investigate the free vibration of antisymmetric angle-ply laminated plates, having one pair of opposite edges simply supported, are develped on the basis of the Yang, Norris and Stavsky (YSN) theory. The equation of motion of the plate are solved by the use of collocation method. A range of results are presented for plates to show the effects of modulus ratio and number of layers on natural frequency. In addition, an analysis of the strain energy distributions is used as an aid for the better understanding of the vibration characteristics of the plates.

두 변이 단순지지된 역대칭 Angle-Ply 적층판의 자유진동에 대하여 Yang, Norris, Stavsky의 YNS 이론을 이용하여, 적층판의 자유진동해석 및 변형에너지 해석을 하였다. 적층판의 운동방정식은 선점법을 사용하여 해석하였고, 탄성계수비와 적층수가 고유진동수에 미치는 영향을 검토하였다. 또한 변형에너지 분포 해석을 이용하여 적층판의 진동특성을 명확히 규명하였다.
