Optimization of Postbuckling-Stiffened Composite Aerostructures
, 2018 Experimental and numerical evidence has shown that the occurrence of secondary instabilities, or mode-jumping, can have a detrimental effect on the structural integrity of thin-skinned stiffened composite panels.

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.This study addresses a critical gap in seismic design codes by evaluating the nonlinear performance of multi‐tiered eccentrically braced frames (MT‐EBFs) and offering practical recommendations for future provisions. MT‐EBFs, an advanced variation of conventional EBFs, incorporate multiple tiers of links and braces within a single story, making them ...

Lateral Postbuckling Analysis of Beam Columns
Journal of Engineering Mechanics, 1994 This is a study of the elastic lateral post buckling response of a simply supported beam under uniform bending acting on the plane of major bending rigidity, in which the effect of an axial compreisson is also included. The study established the stability or instability of the critical state; the initial (nonlinearly elastic) postbuckling equilibrium ...

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.Cone‐shaped membrane‐tensegrity structures are a new system in covering big spans and are usually analyzed as an elastic structure in research and design. This assumption is a simplifying method because of the complexity of membrane materials and its consideration in an analysis.

Load-Carrying Capacity of Ultra-Thin Shells with and without CNTs Reinforcement
Mathematics, 2022 Isotropic ultra-thin shells or membranes, as well as cable–membrane structures, cannot resist loads at the initial state and always require a form-finding process to reach the steady state.

Numerically Predicted Buckling Design Criteria for Elliptical Common Bulkhead Structures
International Journal of Aerospace Engineering, Volume 2026, Issue 1, 2026.A common bulkhead (CB) structure that separates the oxidizer and fuel regions without an interstage single tank reduces the weight of the propellant tanks of launch systems. CB structures can be designed into various shapes, such as hemispherical, elliptical, or torispherical.
