Constrained Willmore Tori and Elastic Curves in 2-Dimensional Space Forms

open access: yes, 2014
In this paper we consider two special classes of constrained Willmore tori in the 3-sphere. The first class is given by the rotation of closed elastic curves in the upper half plane - viewed as the hyperbolic plane - around the x-axis.

The dynamics of electron beam scattering on metal membranes: nanopore formation in metal membranes using transmission electron microscopy

open access: yesNano Convergence, 2018
The dynamics of nanopore formation in metal membranes using the highly focused and high energy electron beams (e-beams) of transmission electron microscopy instruments was investigated.

A Unified Nonlinear Elastic Model for Rock Material

open access: yesApplied Sciences, 2022
Under conditions of low or medium stress, rocks that are in the compression state exhibit perceivable nonlinear elastic characteristics. After a comprehensive review of the existing nonlinear elastic models of rocks and joints, we proposed a new unified ...

Laser induced Zero-Group Velocity resonances in Transversely Isotropic cylinder

open access: yes, 2015
The transient response of an elastic cylinder to a laser impact is studied. When the laser source is a line perpendicular to the cylinder axis, modes guided along the cylinder are generated.

Research on Fracture Toughness of Flattened Brazilian Disc Specimen after High Temperature

open access: yesHigh Temperature Materials and Processes, 2016
Fracture toughness is an important parameter to study fracture characteristic of rock under external loads. Based on splitting tensile test on flattened Brazilian disc specimen of rock after high temperature, load–displacement curves of rock sample in ...

Interlaminate Deformation in Thermoplastic Composite Laminates: Experimental-Numerical Correlation

open access: yesEPJ Web of Conferences, 2010
The interlaminar deformation behaviors of thermoplastic AS4/PEEK composite laminates subjected to static tensile loading are investigated by means of microscopic moiré interferometry with high spatial resolution. The fully threedimensional orthotropic

Elastic Curves With Variable Bending Stiffness

open access: yesStudies in Applied Mathematics
ABSTRACTWe study stationary points of the bending energy of curves subject to constraints on the arc length and the curve's holonomy while simultaneously allowing for a variable bending stiffness along the arc length of the curve. Physically, this can be understood as a model for an elastic wire with isotropic cross section of varying thickness.

Elasticity of polyelectrolyte multilayer microcapsules

open access: yes, 2003
We present a novel approach to probe elastic properties of polyelectrolyte multilayer microcapsules. The method is based on measurements of the capsule load-deformation curves with the atomic force microscope.

Fractal pattern formation at elastic-plastic transition in heterogeneous materials [PDF]

open access: yes, 2009
Fractal patterns are observed in computational mechanics of elastic-plastic transitions in two models of linear elastic/perfectly-plastic random heterogeneous materials: (1) a composite made of locally isotropic grains with weak random fluctuations in ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

open access: yesMolecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.
