INTRODUCTION: Osteoporotic fracture is one of the commonest geriatric orthopaedic problems. The deterioration in microarchitecture and decrease in bone mineral density (BMD) in osteoporotic bone reduce its “holding power” to implants. Subsequently, osteoporotic fractures are difficult to be fixed and remain major challenge to surgeons (1). Intensive in vivo studies are necessary for testing the...

Introduction: Fracture of the tibial and femoral diaphysis constitutes approximately 7% of fractures occurring in children1. Such fractures are commonly repaired by intra-medullary nailing. While removal of implanted nails is often routinely performed after fracture healing it is not always without complication, often due to difficulty or inability to remove the nail.Currently intra-medullary n...

The subsea anchor piles of offshore wind power floating platform structures are mainly subjected to uplift and horizontal loads, this paper focuses on the case loads. A three-dimensional numerical simulation study pullout characteristics suction in clay layers was carried out reveal movement state during pile pullout, range depth at point where is achieved (referred as range), relationship betw...

This article assesses the pullout performance of ribbed metallic strips embedded in fill soils that do not conform to conventional design criteria for mechanically stabilized earth (MSE) walls. These alternative include gravelly and sandy recycled aggregates from construction demolition waste, artificial natural sands, fine-grained lateritic soil. The research included soil characterization tes...

This paper presents an investigation on the bond behavior of carbon fabric-cementitious matrix interface within fabric reinforced cementitious (FRCM) composite. The embedded yarn shows a complicated due to stochastic and incomplete impregnation can be subdivided into outer (impregnated) inner (non-impregnated) parts. Pullout tests were carried out FRCM composite aiming at examining effect betwe...

The toughness of composite materials is size dependent below a critical load transfer length (lT). Fiber-reinforced viscoelastic polymers are uniquely suited to study the size-limited regime because lT these soft composites can be as high several centimeters, in contrast traditional where extremely small, allowing large window for macroscale characterization. In this work, we elucidate paramete...

Abstract An electrophoretic deposition (EPD) process of micro-quartz (MQ) powder is applied to carbon fibers (CFs) with the aim enhance their interfacial bond cementitious matrices and investigate its influence on microstructural mechanical properties CFs itself. The mobility MQ particles negative charge in aqueous media was confirmed by potential sweep experiments zeta-potential measurements. ...

Soil-structure frictional resistance is an important parameter in the design of many foundation systems. The soil-structure interface area responsible for load transferring from structure to surrounding soil. mobilized shaft axially loaded, long slender pile embedded dense, dry sand experimentally and numerically analyzed when subjected pullout force. Experimental setup including instrumented m...
