In order to investigate the pullout resistance of Horizontal-Vertical reinforcement, a “denti-geogrid” was assembled by bonding “denti-strip” with geogrid and tests were carried out. Subsequently, analytical approaches investigated calculate on basis surface sliding model, Perterson Anderson’s Jewell’s Chai’s proposed stress summation model. Moreover, new index named “scale factor” suggested re...
This study presents the results from centrifuge modeling experiments performed to understand effects of temperature changes on vertical pullout capacity scale-model torpedo piles embedded in soft clay layers. The model pile is a pointed stainless-steel cylinder with fins at top, installed by self-weight base layer using stepper motor. An internal electrical resistance heater was used control te...
PURPOSE Absorbable suture anchors offer great advantages but are made of mechanically weak material. The weakest link in the fixation of soft tissue to bone may therefore be the anchor itself. In this study, several commercially available anchors were mechanically tested in vitro. TYPE OF STUDY Biomechanical bench study. METHODS Twelve absorbable suture anchor models were implanted into an ...
Pullout capacity of small ground anchors by direct cone penetration test methods and neural networks
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...
Numerical analysis software based on linear finnite element method and statistical damage theory concrete material has been adopted in this study. Dynamic numerical model of twin fibers pullout test matrix have created by considering the meso-heterogeneity material. The whole process from micro-cracks initiation, propagation to crack penetration simulated. influence stress wave loading peak rat...
OBJECTIVE The partially threaded cancellous lag screw (PTLS) could not provide maximum compressive force (C(MAX)) for compression due to compromised pullout strength (POS). The combined partially threaded cancellous lag screw (CPTLS) could provide higher C(MAX) than PTLS. However, the change of POS at the point of C(MAX) when using CPTLS for compression has never been explored. The aim of this ...
Molecular dynamics (MD) simulations under transverse shear, uniaxial compression, and pullout loading configurations are reported for multiwall carbon nanotubes (MWCNTs) with different fraction of interwall sp3 bonds. The interwall shear coupling in MWCNTs is shown to have a strong influence on load transfer and compressive load carrying capacity. A new continuum shear-coupled-shell model is de...
