We consider the problem of identifying unknown inclusions inside an elastic body by means of traction–displacement relations measured on the boundary. Based on the asymptotic formula of Ammari et al (2003 J. Elast. at press), we propose an algorithm to reconstruct unknown inclusions. The algorithm of this paper detects the location and the elastic moment tensors (elastic Pólya–Szegö tensors) of...

The traction exerted by a cell on a planar deformable substrate can be indirectly obtained on the basis of the displacement field of the underlying layer. The usual methodology used to address this inverse problem is based on the exploitation of the Green tensor of the linear elasticity problem in a half space (Boussinesq problem), coupled with a minimization algorithm under force penalization....

Climbing on vertical concrete structures like bridge pylons or dams is still a great challenge for autonomous robots. This paper presents the forceand traction control system of the climbing robot Cromsci which uses a negative pressure system for adhesion and driven wheels for propulsion. Especially in vertical environments the propulsion system must be able to produce enough force for carrying...

conclusions although skin traction had no effect on analgesic consumption, it significantly decreased the pain at the end of the first day. the application of skin traction in patients with intertrochanteric fractures is recommended. results the severity of pain was significantly decreased in skin traction group only at the end of the first day after traction application (2.7 ± 0.8 vs. 3.3 ± 0....

An experimental protocol is developed to measure the shear strength of NMC811 single crystals within cathode a lithium-ion cell. The placed upon set thick metallic substrates that possess wide range indentation hardness. For each choice substrate, top surface indented by Vickers indenter sufficient depth layer subjected an approximately spatially uniform compressive normal traction equal hardne...

In materials, the evolution of crack surfaces is intimately linked with self-contact occurring between them. The developed contact forces not only mitigate effect stress concentration at tip but also contribute significantly to transfer shear and normal stresses. this article, we present a numerical framework study simultaneous process fracture fracturing surfaces. widely used approach, where c...

A boundary value problem of orthotropic piezoelectric solid circular cylinder which is in the state antiplane shear deformation studied. The whole surface loaded by an equilibrium axial traction. This paper gives analytical solution considered deformation.

purpose: to describe the association between optic disc traction and non-arteritic anterior ischemic optic neuropathy (naion). methods: eighty three eyes of 83 patients with naion were evaluated by optical coherence tomography (oct) for detecting vitreous adhesion to the optic nerve head with separation from adjacent retina (partial posterior vitreous detachment). those who were negative for su...
