Pull-out experiments were performed on four carbon fiber-reinforced polymer (CFRP) ground anchors simulating their applications in rock and soil. The CFRP tendons used in these anchors comprise a single-strap end on both the ground and air sides. On the ground side, the single-strap end is embedded in a cylinder of high-strength grout which fits into the borehole. In rock applications, the grou...

s you'll see, no one can argue that the new and improved Rabbit 3000 8-bit micro doesn't live up to the latter expectation. How new it is, though, is another question. The silicon may be hot off of the assembly line, but the 3000 has roots that go way back. Flash back to the mid-'70s. Messrs, Faggin, Shima, Mazor, et al of Intel sit down to craft a follow-on to their 4004 calculator chip and 80...

polymeric yarns for reinforcing cement composites have got great interest in all over the world. in this research the performance of bonding between nylon tire cord grad yarns, and one kind of cement composite called fine grained concrete was studied. two kinds of nylon cord yarns, nylon 6 and 66, with different finesse were selected. the durability of yarns with time in alkaline media was inve...

In this study, a new medical bone screw was designed and manufactured by Ti6Al4VELI GR23 material and tested in accordance with the ATSM F 543-02 test procedure experimentally. This test is used to measure the axial tensile force required to fail or remove a bone screw from a defined material. Concurrently, 3-D Finite Element Analysis (FEA) models of these medical bone screws were developed to ...

Suction caisson is a type of floor foundation for the offshore structures that is also called suction pile, bucket foundation, suction anchor, or sometimes ridge foundation depending on its application. In two past decades, this type of foundation has been widely used around the world as the fixed offshore foundation, anchor of the floating platforms, as well as the foundation of other marine s...

Fiber shedding is a critical problem in biomedical textile debridement materials, which leads to infection and impairs wound healing. In this work, single fiber pull-out test was proposed as an in vitro evaluation for the fiber shedding property of a textile pile debridement material. Samples with different structural design (pile densities, numbers of ground yarns and coating times) were prepa...

Introduction: The screw biomechanical performance plays a crucial role on the early interfragmentary stability and, in turn, on the fracture healing outcome. To assess the biomechanical performance of the headless compression screws Fixos 4.0, 5.0 & 7.0 mm, interfragmentry compression force and pull-out strength were determined and compared to the Synthes 4.5 & 6.5 mm HCS. Materials & Method: I...
