Influence of Imperfections on Axial Buckling Load of Composite Cylindrical Shells [PDF]

, 2013
There is a strong requirement for more robust, lighter and cheaper launch vehicle structures. Unstiffened composite cylindrical shells, which are essential to the fabrication of launch vehicle airframes, are prone to buckling and are highly sensitive to ...

Determination of Optimal Cylindrical Shells in the Form of Second-Order Surfaces

Structural Mechanics of Engineering Constructions and Buildings
Thin shells with cylindrical and conical middle surfaces are most popular. Many shell-type structures have been built in the form of rotational and translational surfaces, for which there are several dozen optimality criteria.

Steady-State Creep of Circular Cylindrical Shells

Bulletin of JSME, 1970
Steady-state creep of simply supported circular cylindrical shells with open ends under internal pressure is analysed numerically by the extended Newton method combined with the method of finite-difference. Creep theory of Mises type and power creep law are assumed. Numerical calculation is carried out for long and short shells with creep exponents n=1

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix

Advanced Materials, EarlyView.
3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Vibration Power Flow of an Infinite Cylindrical Shell Submerged in Viscous Fluids

Shock and Vibration, 2020
In the previous investigations of the vibroacoustic characteristics of a submerged cylindrical shell in a flow field, the fluid viscosity was usually ignored.

Free vibration of an oblique circular cylindrical shell

The Journal of the Acoustical Society of America, 1985
An analysis is presented for the free vibration of an oblique circular cylindrical shell. For this purpose, the shell is transformed into a circular cylindrical shell of unit axial length by a transformation of variables. The deflection displacements of the transformed shell are expressed in a series of the products of the eigenfunctions of an axial ...

Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

Advanced Materials, EarlyView.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Vibration of a Combination of Circular Plates and Cylindrical Shells : 2nd Report, Cylindrical Shells with a Circular Plate in the Intermediate Section

Transactions of the Japan Society of Mechanical Engineers, 1970
The present paper is primarily devoted to the study of the vibrations of a cylindrical shell with a panel or a flange of a circular plate in the intermediate section. Frequencies and displacements are determined by means of minimizing the total Lagrangian.

Fiber‐Format Flexible Linear Electrostatic Motors

Advanced Materials, EarlyView.
A flexible coaxial fibre‐format electrostatic motor enables backdrivable and reversible linear actuation with high force density and functionality under bending, offering a scalable actuation platform for soft and wearable robotics. ABSTRACT Linear motion is fundamental to robotics, yet existing solutions are either rigid electromagnetic motors or ...
