Comparison of new Design Guidelines for Composite Cylindrical Shells prone to Buckling [PDF]

, 2013
Currently, imperfection sensitive shell structures prone to buckling are designed according to the NASA SP-8007 guideline, from 1968, using its conservative lower-bound curve.

Effect of ribs on sound radiation characteristics of double cylindrical shell based on statistical energy analysis

Zhongguo Jianchuan Yanjiu, 2018
[Objectives] The main structure of a submarine is a ring-stiffened cylindrical shell. At present, most research into the effects of ribs on the acoustic radiation characteristics of cylindrical shells is concentrated on middle and low frequencies, but ...

Upcycling Keratin‐Based Textile Waste Into High‐Performance Hybrid Fibers Via Tuning the Interfacial Interactions

Advanced Functional Materials, EarlyView.
Keratin recovered from animal‐hair textile waste is fractionated and blended with cellulose to produce continuously spun hybrid fibers. Selecting the high‐molecular‐weight keratin fraction enables 30 wt.% keratin incorporation while maintaining high strength in dry and wet states.

Analysis of bearing capacity and blast resistance of double stiffened pressure-resistant cylindrical shell structure

Zhongguo Jianchuan Yanjiu
ObjectiveIn order to explore the effects of different stiffening configurations on the bearing capacity and anti-blast performance of double stiffened cylindrical shells, a numerical study is made of the responses of four kinds of double stiffened ...

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

Advanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Analysis on Forced Vibration of Thin-Wall Cylindrical Shell with Nonlinear Boundary Condition

Shock and Vibration, 2016
Forced vibration of thin-wall cylindrical shell under nonlinear boundary condition was discussed in this paper. The nonlinear boundary was modeled as supported clearance in one end of shell and the restraint was assumed as linearly elastic in the radial ...

Nitride MXenes Beyond Carbides: Bridging the Gap Between Computational Prediction and Experimental Realization

Advanced Functional Materials, EarlyView.
Nitride MXenes remain constrained by a persistent gap between computational prediction and experimental realization. This Review identifies the thermodynamic, kinetic, and chemical barriers limiting their synthesis, critically evaluates emerging fabrication routes, and proposes a multidimensional computational‐experimental framework to accelerate the ...

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications

Advanced Functional Materials, EarlyView.
Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Analytical Calculation of Cylindrical Shells in the Form of Second-Order Algebraic Surfaces

Structural Mechanics of Engineering Constructions and Buildings
When choosing the shape of a shell, one should strive for the boundary conditions to ensure momentless behavior of the shell. Second-order algebraic surfaces include three degenerate surfaces: parabolic, elliptic, and hyperbolic cylindrical surfaces, and

The vibration of rotating cylindrical shells.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1986
The vibration of rotating cylindrical shells is examined with relation to a thin roatating ring. The results of the experiment and the theoretical analyses for four kinds of boundary conditions (i. e., (A) both ends clamped ; (B)simply supported without axial constraint ; (C) simply supported with axial constraint ; and (D) a clamped end at one end, a ...
