Thermal buckling of laminated cross-ply oval cylindrical shells

Thermal postbuckling of shear-deformable anisotropic laminated cylindrical shells with temperature-dependent properties

“…We first examine the valid of the present formulation by comparison of thermal buckling of cross-ply cylindrical shells (L/R¼0.5, R/t ¼200, 300, 400, 500) for which analysis results are available in the literature [3] and [11]. The buckling temperatures of (0/90) and (0/90/0) laminated cylindrical shells subjected to uniform temperature rise are presented in Table 2.…”

“…Because of the definition of e given in Eq. (11) [29]). In practice, the shell structure will have Z Z10, so that we always have e{1.…”

“…Many thermal buckling studies have been made for laminated plates and shells [1][2][3][4][5][6][7][8][9][10][11]. Among these, Birman and Bert [1] investigated the buckling and postbuckling response of composite shells subjected to high temperature.…”

“…Arciniega et al [10] studied the postbuckling response of laminated cylindrical shells to produce much more accurate results using a third-order shear deformation shell theory. Based on higher-order shear deformation theory, thermal buckling behavior of laminated cross-ply oval cylindrical shells is analyzed by Patel et al [11][12][13] using finite element approach, which accounted for influence of transverse shear and transverse normal deformations, shell geometry, ovality, and lay-up on the critical temperature parameter of laminated oval cylindrical shells. It is noted that in most of the foregoing studies, a membrane prebuckling state is assumed.…”
