Diametral compression tests were performed on pultruded composite rods comprised of unidirectional glass or carbon fibers in a common matrix. During compression tests, acoustic emission (AE) activity was recorded and images were acquired from the sample for analysis by digital image correlation (DIC). In both composite systems, localized tensile strain developed in the transverse plane under th...

This paper aims to accurately realize given traffic split ratios in switches with small performance degradation. For given traffic split ratios calculated mathematically by TE algorithms in the control plane, the load distribution mechanisms in the data plane implement such splits without breaking flows. Treating all flows equally, the state-of-the-art approaches deployed in switches do not pro...

INTRODUCTION The follower load represents the path of the internal force resultant passing through the centers of rotation of successive spinal segments. An ideal follower load is perpendicular to the mid-plane of the intervertebral disc and minimizes shear and bending moments at all levels. Patwardhan and colleagues showed that a follower compressive preload increases the stability and load ca...

Overexertion and pain of the musculoskeletal system may occur partly owing to load application by the equipment. Both the weight of equipment and the duration of loading are relevant. The aim of the present study was to examine the extent of loading and resultant strain in the trunk muscles. Therefore, the trunk posture of soldiers and muscular activity in reaction to different equipment compon...

The experimental method of caustics was used for the evaluation of the stress-singularities created by concentrated oblique load applied at the apex of a wedge or on the horizontal straight boundary of a half-plane. The wedge was considered to be elastic, isotropic and under generalized plane stress conditions. According to the method of caustics, the light rays impinging normally at the thin p...

There is a lack of knowledge regarding the parameters needed for effective seismic performance assessment historical stone masonry buildings. The paper presents results an extensive experimental campaign consisting four compression and fifteen in-plane cyclic shear tests on three-leaf ashlar walls its constituents. morphology, level vertical load, testing boundary conditions were systematically...

A computational method is presented as a for solving plane contact problem of the theory elasticity to determine strength and tribological durability sliding bearings. The effect load radial clearance on initial pressures their reduction due wear studied. bearing estimated. Qualitative quantitative regularities changes in parameters from factors under study are established. In particular, it ha...

steel structures are usually built with some defects. according to the standard building codes, the central axes of the bracing members should go through the beam-column joints, however, in most of the braced steel structures, bracing members are unintentionally connected eccentrically. this paper presents a numerical investigation on performance analysis of cbfs (concentrically braced frames) ...
