Abstract

Presented in this paper are the results of an analytical investigation pertaining to the elastic buckling behavior of transversely isotropic plate with variable width subjected to unequal uniaxial compression forces at the ends and in-plane shear forces at the sides. The existing analytical solution developed for the isotropic plates is extended so that the transversely isotropic material properties can be taken into account in the plate buckling analyses. For the derivation of buckling equation the power series solution is employed. Graphical forms of results for finding the buckling strength of tapered plates are presented. In addition, the finite element analysis is also conducted. The results are compared and discussed.

본 연구는 폭이 변하는 transversely isotropic 판에서 평행한 변에 서로 크기가 다른 면내 축방향 압축력이 작용하며, 경사진면에는 면내 전단력이 작용하는 경우 판의 탄성좌굴거동에 관한 해석적 연구결과이다. 폭이 변하는 등방성판의 좌굴해석을 위해 개발된 기존의 이론적 해를 확장하여 transversely isotropic 재료의 역학적 성질을 고려한 좌굴해석을 할 수 있도록 하였다. 이론식은 power series를 사용하여 유도하였으며, 유한요소해석을 부가적으로 수행하고 그 결과를 이론식을 사용한 해석결과와 비교, 검토하였다.
