Nonlocal Elasticity Response of Doubly-Curved Nanoshells [PDF]

open access: yesSymmetry, 2020
In this paper, we focus on the bending behavior of isotropic doubly-curved nanoshells based on a high-order shear deformation theory, whose shape functions are selected as an accurate combination of exponential and trigonometric functions instead of the classical polynomial functions.

Curves in the Lorentz-Minkowski plane: elasticae, catenaries and grim-reapers

open access: yesOpen Mathematics, 2018
This article is motivated by a problem posed by David A. Singer in 1999 and by the classical Euler elastic curves. We study spacelike and timelike curves in the Lorentz-Minkowski plane 𝕃2 whose curvature is expressed in terms of the Lorentzian ...

Axial Compression Behaviour and Modelling of Pultruded Basalt-Fibre-Reinforced Polymer (BFRP) Tubes

open access: yesBuildings, 2023
Laminated fibre-reinforced polymer (FRP) tubes are increasingly used as compression members in large-span spatial structures due to their high bearing capacity, corrosion resistance, and superior stability compared to high-strength steel pipes.

Dynamic deformation characteristics of unsaturated silt over a wide suction range

open access: yesYantu gongcheng xuebao, 2019
By using a suction-controllable dynamic triaxial testing apparatus, a series of dynamic deformation tests are carried out on a unsaturated silt subjected to wide suctions imposed by the axial translation technique and vapor equilibrium method with ...

Characteristics of energy evolution during total stress-strain in rocks under uniaxial compression

open access: yesMeikuang Anquan, 2023
To study the energy evolution of rocks under uniaxial compression, uniaxial compression and uniaxial step loading and unloading tests were performed on granite, sandstone, and coal, and the stress-strain curves under different conditions were obtained ...

Elastic Analysis of Irregularly or Sparsely Sampled Curves

open access: yesBiometrics, 2022
Abstract We provide statistical analysis methods for samples of curves in two or more dimensions, where the image, but not the parameterization of the curves, is of interest and suitable alignment/registration is thus necessary. Examples are handwritten letters, movement paths, or object outlines.

Elastic visco-plastic model for soft clay based on isochronous curves

open access: yesYantu gongcheng xuebao, 2018
The deformation of soft clay is closely related to the time, including both consolidation effect and creep effect, between which the interaction determines the settlement and long-term settlement of soft soils.
