Influence of Biological Pretreatment of Wooden Dowels on Strength of Rotary Welded Joints

BioResources, 2023
Welding wood achieves joints whose strength is comparable with the strength of glued joints. When welding, the top of the dowel is not welded because of the lack of melted lignin.

Enhancing spinal bone anchor pull-out resistance with an L-shaped anchor.

PLoS ONE
The success rate of spinal fusion surgery is mainly determined by the fixation strength of the spinal bone anchors. This study explores the use of an L-shaped spinal bone anchor that is intended to establish a macro-shape lock with the posterior cortical

Enhancement of compaction grouting on a compaction-grouted soil nail in sand

Yantu gongcheng xuebao, 2021
The compaction grouting is an important factor in enhancing the performance of the newly developed compaction-grouted soil nail. Based on the self-developed large-scale model system, two series of pull-out tests with and without compaction grouting are ...

Pull-Out Properties of Nano-Processed Para-Aramid Fabric Materials in Soft Ballistic: An Experimental Analysis

Applied Sciences
Single and multiple pull-out properties of a nano-processed para-aramid fabric structure were investigated. The nano pull-out behavior exhibited three distinct regions, namely crimp extension, interlacement rupture, and stick-slip. Multiple yarn pull-out

The accuracy and effectiveness of automatic pedicle screw trajectory planning based on computer tomography values: an in vitro osteoporosis model study

BMC Musculoskeletal Disorders, 2022
Background Pedicle screw placement in patients with osteoporosis is a serious clinical challenge. The bone mineral density (BMD) of the screw trajectory has been positively correlated with the screw pull-out force, while the computer tomography (CT ...

Pull-out mechanism of continuous ball shape anchors in transparent soil

Yantu gongcheng xuebao, 2017
A physical modelling system is developed to study the pull-out mechanism of embedded soil anchors using transparent soil and particle image velocimetry (PIV). In the system, two different continuous ball shape anchors are set in the experiment to observe
