A study on the use of the Osstell apparatus to evaluate pedicle screw stability: An in-vitro study using micro-CT. [PDF]
PLoS ONE, 2018 Pull-out force and insertion torque have not been generally used as intraoperative measures for the evaluation of pedicle screw stability because of their invasiveness.

Thin Polymer Film Force Spectroscopy: Single Chain Pull-out and Desorption [PDF]
ACS Macro Letters, 2020 Atomic force microscopy (AFM) was utilized to investigate the force associated with chain pull-out and single chain desorption of poly(styrene-co-butadiene) random copolymer thin films on mica, silicon, and graphite substrates. Chain pull-out events were common and produced a force of 20-25 pN. The polymer desorption force was strongest on the graphite

Experimental and Analytical Study on Pull-out Force of Steel Fiber-Reinforced Concrete Blocks
Diyala Journal of Engineering Sciences, 2022 Reinforcing bar bonding in concrete is essential for reinforcing bar anchoring and reinforced concrete cracking control. A pull out test of a reinforcing bar embedded in a concrete block is commonly used to determine it. When compared to plain concrete,

A Mathematical Model for A Cladding Fastener to Estimate the Maximum Pull-Out Force Capacity [PDF]
Journal of Physics: Conference Series, 2020 Abstract In the last few years, considerable attention has been paid to the roof cladding systems due to their progressive use in the construction of low-rise buildings. The design of such systems has been gaining importance since they are subjected to severe damage and failure caused by high wind events, particularly at their fastener ...
