Local Buckling Failure of Buried Pipeline under the Action of Oblique-slip Fault

Shiyou jixie, 2022
In practice,many pipelines will cross oblique-slip faults,but presently there is little research on the buckling failure of buried pipelines under the action of both horizontal and vertical oblique-slip faults.Therefore,based on ABAQUS finite element ...

The origin of compression influences geometric instabilities in bilayers [PDF]

, 2018
Geometric instabilities in bilayered structures control the surface morphology in a wide range of biological and technical systems. Depending on the application, different mechanisms induce compressive stresses in the bilayer.

On Non-Axisymmetric Buckling Modes of Inhomogeneous Circular Plates

Vestnik St. Petersburg University, Mathematics, 2021
Unsymmetrical buckling of nonuniform circular plates with elastically restrained edge and subjected to normal pressure is studied in this paper. The asymmetric part of the solution is sought in terms of multiples of the harmonics of the angular coordinate.

Supraparticles Composed of Graphitic Carbon Nitride Nanoparticles and Silica‐Supported Horseradish Peroxidase as Customizable Hybrid Catalysts for Photo‐Biocatalytic Cascade Reactions in Continuous Flow

Advanced Functional Materials, EarlyView.
Herein presented supraparticles combine the nanoparticulate photocatalyst graphitic carbon nitride with the enzyme horseradish peroxidase, which is immobilized on silica nanoparticles. In an optimized compatibility range, both catalysts operate effectively within the hybrid supraparticles and catalyze a cascade reaction consisting of the photocatalytic

Effect of an Electron-phonon Interaction on the One-electron Spectral Weight of a d-wave Superconductor [PDF]

, 2003
We analyze the effects of an electron-phonon interaction on the one-electron spectral weight A(k,omega) of a d_{x^2-y^2} superconductor. We study the case of an Einstein phonon mode with various momentum-dependent electron-phonon couplings and compare ...

Golden‐Ratio–Guided Aperiodic Architected Metamaterials with Simultaneously Enhanced Strength and Toughness

Advanced Functional Materials, EarlyView.
Guided by the golden ratio, a class of aperiodic architected metamaterials is introduced to address the intrinsic trade‐off between strength and toughness. By unifying local geometric heterogeneity with global order, the golden‐ratio‐guided aperiodic architecture promotes spatial delocalization of damage tolerence regions, leading to more tortuous ...

Exploiting Two‐Photon Lithography, Deposition, and Processing to Realize Complex 3D Magnetic Nanostructures

Advanced Functional Materials, EarlyView.
Two‐photon lithography (TPL) enables 3D magnetic nanostructures with unmatched freedom in geometry and material choice. Advances in voxel control, deposition, and functionalization open pathways to artificial spin ices, racetracks, microrobots, and a number of additional technological applications.

Mode-Reduction Applied to Initial Post-Buckling Behavior

, 1994
This paper presents a perturbation approach for analyzing the (initial) post-buckling behavior of elastic structures. In this perturbation a small number of buckling modes is taken into account. This approach results in a potential energy function which is defined in terms of amplitudes of the selected modes.
