RISDiscussion of “<i>Effect of Axial Compressibility on Buckling of Columns</i>” by Charles W. Bert (March, 1990, Vol. 116, No. 3)
Publisher: American Society of Civil Engineers
Cylindrical Buckling Load of Laminated Columns
Publisher: American Society of Civil Engineers
Abstract: The cylindrical buckling load of a composite laminated column is derived from plate theory. The effect of lamina orientation is taken into account by treating the stiffness parameter as a matrix product rather than as a ...
Buckling and Sensitivity to Imperfection of Conical Shells Under Dynamic Step-Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general nonlinear dynamic analysis, based on Donnell’s shell-type theory, is developed for an arbitrary imperfect isotropic conical shell. It is used for studying dynamic stability and imperfection ...
Post-Buckling Analysis of Stiffened Laminated Panel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An analytical-numerical procedure is applied to investigate the post-buckling behavior of a composite laminated stiffened panel. The panel is modeled by plate elements for which the nonlinear ...
Imperfection Sensitivity of Laminated Cylindrical Shells According to Different Shell Theories
Publisher: American Society of Civil Engineers
Abstract: The imperfection sensitivity of laminated cylindrical shells is considered—via the initial postbuckling analysis—on the basis of three different shell theories: Donnell in 1933; Sanders in 1963; and Timoshenko in 1961. The ...
Buckling of Delaminated Composite Beams with Shear Deformation Effect
Publisher: American Society of Civil Engineers
Abstract: A general 1D model of composite delaminated beams with shear deformation effect is derived for buckling behavior. The constitutive models of composite laminated beams are derived from the classical 2D laminate theory. The ...
Postbuckling Analysis of Geometrically Imperfect Conical Shells
Publisher: American Society of Civil Engineers
Abstract: A suitable postbuckling analysis, based on geometrically nonlinear behavior, is developed for arbitrary imperfect conical shells. The conical shell was chosen as a representative case exhibiting the entire range of sensitivity ...
Postbuckling analysis of stiffened Laminated Curved Panels
Publisher: American Society of Civil Engineers
Abstract: An analytical solution is presented for the postbuckling behavior of composite laminated stiffened curved panels, whether curved in a longitudinal or lateral direction (not both). The nonlinear equations for the model are ...
Discontinuities in the Sensitivity Curves of Laminated Cylindrical Shells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The discontinuity in the sensitivity of laminated cylindrical shells is investigated via the initial post-buckling analysis. A general procedure for sensitivity, based on Koiter’s parameters and ...
Efficient Dynamic Reanalysis of Structures
Publisher: American Society of Civil Engineers
Abstract: The combined approximations approach, developed originally for linear static reanalysis, is used for dynamic reanalysis of structures. The approach is based on the integration of several concepts and methods, including ...
