Fully grouted bolts are widely used in engineering. In order to deeply understand the load-transfer mechanism of a fully bolt, it is necessary analyze and study its mechanical behavior under axial cyclic load. First all, based on idea discretization force balance analysis each mass spring element, this proposes method for analyzing bolt—the element method. Second, model bolt established by usin...
Orthopaedic implants experience large cyclic loads, and pre-clinical analysis is conducted to ensure they can withstand millions of loading cycles. Acetabular cup developments aim to reduce wall thickness to conserve bone, and this produces high pre-stress in modular implants. As part of an implant development process, we propose a technique for preclinical fatigue strength assessment of modula...
Abstract Increasing of ballast layer bearing capacity is a widespread problem during the operation and maintenance railway track nowadays. It known that with an increase passed tonnage, tends to become contaminated both by products its own crushing external weeds which rapidly leads strength operational characteristics degradation crushed stone ballast. In this study, attempt was made simulate ...
BACKGROUND Although surgical repair has been reported to provide improved outcomes compared with nonoperative treatment in the management of complete proximal hamstring origin avulsions, no intact or avulsion repair biomechanical data exist to support various repair strategies or guide postoperative rehabilitation. PURPOSE To compare failure load among 4 proximal hamstring tendon conditions: ...
