Abstract

Optimization Analysis of angle-ply laminated shells, having one pair of opposite edges supported, are investigated on the basis of the first-order shear deformation theory. The equations of motion of the shell are solved by the use of ritz method. A range of results are presented for composite shells to show the effects of lamination angle 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 shells.

Angle-Ply 적층쉘의 진동특성에 관한 최적화해석을 위해 1차전단변형이론에 의한 Ritz Method를 이용하여 이론적으로 해석하고, 수치해석에 의해 고유진동수와 진동모드를 해석하여 적층수, 쉘의 지지조건, 적층순서에 미치는 영향을 정량적으로 검토하여 적층복합원통쉘의 기본고유진동수의 최적화를 위한 최적인 적층구성에 미치는 영향을 명확히 규명하고자 한다.
