Experimental Study of Buckling of Reinforced Conical Composite Shell Under Hydrostatic Loading [PDF]

open access: yesMechanics of Advanced Composite Structures, 2022
Cone shells due to their special aerodynamic shape are the main component for air-space transport and submarine structures. The application of composite materials in these structures leads to achieving lower strength-to-weight ratios.

Effects of toroidal transition on strength and stability of submarine's cone-cone connection structure

open access: yesZhongguo Jianchuan Yanjiu, 2020
[Objectives] The cone-toroid-cone structure is a new type of structure to solve the problem of stress concentration at the joint of two conical shells with different angles in a pressure hull of submarine.

INFLUENCE OF EDGE REINFORCING RING ROTATION ON LOAD CARRYING CAPACITY OF CONICAL SHELLS LOADED BY EXTERNAL PRESSURE

open access: yesPerner’s Contacts, 2022
The aim of the article is to present a part of the problem of calculating the load carrying capacity of conical shells, which by their dimensions and selected boundary conditions do not comes under within the scope the standards.

A Preliminary Study Was Conducted on the Compressive Strength and Flow Performance of Environmentally Friendly UHPC-SCA

open access: yesBuildings, 2023
This research paper explores using marine shells as coarse aggregates in producing seawater sea sand UHPC-CA. The study examined factors such as coarse aggregates (granite, oyster shell, and cone shell), fine aggregates (sea sand and river sand), fiber ...

Implosion of Indirectly Driven Reentrant-Cone Shell Target [PDF]

open access: yesPhysical Review Letters, 2003
We have examined the implosion of an indirectly driven reentrant-cone shell target to clarify the issues attendant on compressing fuel for a fast ignition target. The target design is the hydrodynamic equivalent of a NIF cryoignition target scaled to be driven by Omega. Implosions were imaged with backlit x radiographs and modeled with LASNEX.

Shocks, Seyferts and the SNR connection: a Chandra observation of the Circinus galaxy [PDF]

open access: yes, 2012
We analyse new Chandra observations of the nearest (D=4 Mpc) Seyfert 2 active galaxy, Circinus, and match them to pre-existing radio, infrared and optical data to study the kpc-scale emission.

GLASS: Generator for Large Scale Structure

open access: yesThe Open Journal of Astrophysics, 2023
We present GLASS, the Generator for Large Scale Structure, a new code for the simulation of galaxy surveys for cosmology, which iteratively builds a light cone with matter, galaxies, and weak gravitational lensing signals as a sequence of nested shells ...

Electron Precipitation Observed by ELFIN Using Proton Precipitation as a Proxy for Electromagnetic Ion Cyclotron (EMIC) Waves

open access: yesGeophysical Research Letters, 2023
Electromagnetic ion cyclotron (EMIC) waves can drive radiation belt depletion and Low‐Earth Orbit satellites can detect the resulting electron and proton precipitation.

Peanut Shell Derived Carbon Combined with Nano Cobalt: An Effective Flame Retardant for Epoxy Resin

open access: yesMolecules, 2021
Biomass-derived carbon has been recognised as a green, economic and promising flame retardant (FR) for polymer matrix. In this paper, it is considered that the two-dimensional (2D) structure of carbonised peanut shells (PS) can lead to a physical barrier
