A numerical investigation into the plastic buckling paradox for circular cylindrical shells under axial compression [PDF]

, 2014
It is widely accepted that for many buckling problems of plates and shells in the plastic range the flow theory of plasticity leads to a significant overestimation of the buckling stress while the deformation theory provides much more accurate ...

Buckling Behavior of Substrate Supported Graphene Sheets. [PDF]

Materials (Basel), 2016
The buckling of graphene sheets on substrates can significantly degrade their performance in materials and devices. Therefore, a systematic investigation on the buckling behavior of monolayer graphene sheet/substrate systems is carried out in this paper by both molecular mechanics simulations and theoretical analysis. From 70 simulation cases of simple-

BUCKLING ASSESSMENT OF IMPERFECT CYLINDRICAL SHELLS UNDER AXIAL LOADS USING A GEP TECHNIQUE [PDF]

e-GFOS, 2018
Determination of buckling behavior of shell structures has long been identified as a challenging task. This is largely because the buckling behavior is masked by local large deformations, which occur once the critical load is reached.

Buckling analysis of FML cylindrical shells under combined axial and torsional loading [PDF]

Mechanics of Advanced Composite Structures, 2020
Generally, in-served cylindrical shells buckling usually takes place not merely under one of the basic loads, i.e., axial compression, lateral pressure, and torsion, but under a combination of them.
