BACKGROUND AND PURPOSE The most frequently used bones for mechanical testing of orthopedic and trauma devices are fresh frozen cadaveric bones, embalmed cadaveric bones, and artificial composite bones. Even today, the comparability of these different bone types has not been established. METHODS We tested fresh frozen and embalmed cadaveric femora that were similar concerning age, sex, bone mi...

in this paper, dissimilar resistance spot welding of aisi 1075 eutectoid steel to aisi 201 stainless steel is investigated experimentally. for this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. the effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...

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...

Abstract The tests described in this paper were aimed at evaluating the tensile capacity of anchorages connecting an automated pallet warehouse with existing RC foundation. is a new steel structure erected place previous collapsed due to Emilia earthquake, but whose foundation remained undamaged. investigated fastening consists 10 post-installed, bonded threaded rods diameter ( d ) and embedmen...

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...
