Bolt Pull-Out Tests of Anchorage Body under Different Loading Rates

Analysis of Fractal Characteristic of Fragments from Rock Burst Tests under Different Loading Rates

Original scientific paper Rock burst is a common serious geological hazard in underground engineering, which seriously affects the progress of projects. The mechanism of rock burst can be explained by the distribution law of rock fragments and its fractal characteristics. A simulation experiment of rock burst was conducted with the granite samples under a biaxial loading machine system to analy...

Effect of Geogrid Aperture Size and Soil Particle Size on Geogrid-Soil Interaction under Pull-Out Loading

Fracture Mechanics of the Microbond and Pull-out Tests

The properties of the fiber/matrix interface in composites have an influence on their overall performance. Common methods for studying the interface are micromechanical tests that load a single fiber/matrix interface to failure. Two popular tests are the microbond test [1] and the single-fiber, pull-out test [2]. In a microbond test a droplet of matrix is sheared off the fiber by pulling the fi...

Articular Chondrocyte Mechanics at Different Loading Rates

INTRODUCTION Mechanical impact loading is known to cause cell death and to lead to the onset and progression of osteoarthritis [1]. In order to understand why in-situ cells die readily following impact loading but remain unaffected when the same load is applied at a slow rate, we used a Finite Element model of articular cartilage and chondrocytes to study the in-situ cell mechanics, which canno...

Evaluation of the Effect of Sodium Hypochlorite Irrigant on Pull-out Bond Strength of FRC Posts Using Different Resin Cements

Introduction: To evaluate the effects of using sodium hypochlorite irrigant on pull-out bond strength of self-etch and self-adhesive resin cements to dentin. Methods: Sixty intact premolars were decoronated and the root canals were prepared by step-back technique. The teeth were divided into two groups according to the irrigant used during root canal treatment: 5.25% sodium hypochlorite and nor...
