Nonlinear buckling analysis of porous-core FG-GPLRC toroidal shell segments with generalized meridional curvature reinforced by orthogonal stiffeners

Vietnam Journal of Mechanics
By utilizing the Donnell shell theory with von K\'{a}rm\'{a}n strain-displacement relationship, the nonlinear buckling behavior of porous core functionally graded graphene platelet-reinforced composite (FG-GPLRC) toroidal shell segments with generalized

Buckling, Postbuckling and Imperfection Sensitivity Analysis of Different Type of Cylindrical Shells by Hui\u27s Postbuckling Method [PDF]

, 2013
Hui and Chen (1986) were the first to show that the well-known Koiter’s General Theory of Elastic Stability of 1945 can be significantly improved by evaluating the postbuckling b coefficient at the actual applied load, rather than at the classical ...

Postbuckling of nano rods/tubes based on nonlocal beam theory

, 2009
This paper is concerned with the postbuckling problem of cantilevered nano rods/tubes under an end concentrated load. Eringen's nonlocal beam theory is used to account for the small length scale effect. The governing equation is derived from statical and

Postbuckling Analysis of Stringer-Stiffened Composite Laminated Cylindrical Panels

, 1995
The postbuckling behavior of stiffened composite cylindrical panels was studied analytically and experimentally. Progressive failure analysis was implemented for the prediction of failure characteristics and postbuckling ultimate load.
