Dynamic Finite Element Analysis of Impulsive Stress Waves Propagating from the Greater Trochanter of the Femur by a Sideways Fall [PDF]

open access: yes, 2015
Fall accidents are a common cause of femoral fracture in the elderly. The greater trochanter of the femur is often subjected to impact loading by a sideways fall, and thus it is worth studying the impulsive stress waves propagating in the femur.

Evidence for realignment of the charge density wave state in ErTe$_3$ and TmTe$_3$ under uniaxial stress via elastocaloric and elastoresistivity measurements

open access: yes, 2022
We report the evolution of a charge density wave (CDW) state in the quasi-2D rare-earth tritellurides ($R$Te$_3$ for $R$=Er,Tm) as a function of in-plane uniaxial stress.

Influence of Cracking on Deflections of Concrete Box Girder Bridges

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2012
The problem of cracking and long-term deflection in larger-span prestressed concrete box girder bridges exists throughout the world and has restricted the development of long-span concrete bridges to some extent.

Experimental study on spalling of deep rock under half sine stress wave disturbance

open access: yesYantu gongcheng xuebao, 2022
For the spalling failure phenomenon of deep rock under the action of stress wave disturbance, based on the one-dimensional elastic wave theory, the propagation mechanism of a simple half sine stress wave in a single rock member is clarified, and the ...

Influence of matrix toughness and interfacial strength on the toughness of epoxy composites with ductile steel fabric reinforcement [PDF]

open access: yes, 2015
In the last decades, several studies have been performed on polymers reinforced with steel cords or wires. However, the diameter of these steel reinforcements was still quite large (200 micron and more).

The verification of a new approach to the experimental estimation of tensile forces in prestressed structural elements by method based on the magnetoelastic principle

open access: yesMATEC Web of Conferences, 2017
There are a large number of civil engineering structures where the important structural elements are loaded by large tensile forces. In many practical cases, it is significant to know the current value of tensile force or prestressed stress in these ...

Compressive and tensile axial strain reduced critical currents in Bi-2212 conductors [PDF]

open access: yes, 1995
Mono and multifilamentary wires of BSCCO-2212 in Ag matrix are investigated in an axial strain experiment. The superconducting samples are soldered to a substrate that is bend in order to achieve a compressive or tensile axial strain. The I/sub c/-strain
