Thermal postbuckling analysis of laminated cross-ply truncated circular conical shells

On nonlinear thermal buckling analysis of cylindrical shells

“…Symmetric and asymmetric modal deformations of shells of revolution at the number of the dominant circumferential mode (n) are offered as [6][7][8][9][10][11][12][13] where the terms with superscripts 0 and (c i ,s i ) represent symmetric and asymmetric deformations, respectively, and the number of the Fourier series terms is introduced with…”

“…Under certain circumstance such a versatile numerical method may be combined with analytical methods to enhance both accuracy and efficiency of the underlying numerical investigation. Patel et al [6][7][8][9][10] employed the semi-analytical finite element formulation to investigate nonlinear buckling of laminated composite shells under mechanical and thermal loadings. Hong and Teng [11] presented a semi-analytical finite element formulation for the nonlinear analysis of shells.…”

Postbuckling of angle-ply laminated cylindrical shells with meridional curvature

“…The governing equations, derived using the condition for the extremum of total potential energy consisting of strain energy and potential energy of applied external forces, are written as [16][17][18][19] The detailed description of the semi-analytical finite element formulation and its validation for buckling/postbuckling studies of laminated conical/cylindrical shells has been presented in Refs. [16][17][18][19] and is omitted here for the sake of brevity.…”

Buckling of FGM hybrid truncated conical shells subjected to hydrostatic pressure

“…There are fewer research works about stability problems of the FGM conical shells since there are some other difficulties like theoretical analysis and complexity of mathematics can be added to ones mentioned above (see, for example, Sofiyev [43,44], Patel et al [45], Bhangale et al [46], Sofiyev et al [47,48]). …”
