Tubular Bending and Pull-Out Forces in High-Curvature Well Bores
Journal of Energy Resources Technology, 1991This paper is concerned with drag forces developed on tubulars in high-curvature well bores typically found in drainhole and horizontal drilling. The dog-leg severity of these types of boreholes are considerably higher than those typically found in conventional directional drilling.

Pulled Out or Pushed Out? Declining Male Labor Force Participation
Federal Reserve Bank of San Francisco, Working Paper SeriesThe fraction of men working in the United States has declined consistently since the 1950s. This has contributed to slower labor force growth and resulted in considerable gaps between labor force participation in the U.S. and its industrialized peers. In this paper we examine the drivers of this trend, focusing specifically on prime-age men (aged 25–54)

The American Journal of Sports Medicine, 1998
Recently, increased interest in biodegradable interference screws for bone-tendon-bone graft fixation has led to numerous screws becoming available. The implants are made from different polymers and have different designs, which might influence their mechanical properties.

Pull-out forces in shear connectors in composite beams with large web openings
Journal of Constructional Steel Research, 2013Abstract Composite beams with large web openings are often used, and their design is controlled by Vierendeel bending at the four corners of each opening, which is assisted by local composite action with the floor slab. Development of this Vierendeel bending resistance may be limited by pull-out failure of the shear connectors.

Interpretation of the force trace for Kevlar/epoxy single filament pull-out tests
Fibre Science and Technology, 1982Abstract In this paper, results of a single filament pull-out test on Kevlar/epoxy are reported and analysed. The meaning of the force versus displacement (time) trace is clarified based on a mechanics model: the first peak is debonding plus slip; subsequent high peaks are jamming and slipping of the damaged fibre; low and varying force is frictional

Measurement of the Pull-out Force at Different Rates of Loading
SP-155: Testing of Fiber Reinforced Concrete, 1995With the objective of understanding the reinforcing mechanisms of fibers in steel fiber reinforced concrete, the adherence between the fiber and the matrix is studied by conducting pull-out test of fibers from a cementitious matrix. In this paper the effect of factors such as loading rate, inclination of fibers, and number of fibers have been ...

[Design on tester of pull-out force for orthodontic micro implant].
Zhongguo yi liao qi xie za zhi = Chinese journal of medical instrumentation, 2014A special device for measuring the pull-out force of orthodontic micro implant was designed, which has the characteristics of simple construction and easy operation, and can be used to detect the pull-out-force of orthodontic micro implant. The tested data was stored and analyzed by a computer, and as the results, the pull-out-force curve, maximum pull-

Screw Pull-out Force is Dependent on Screw Orientation in an Anterior Cervical Plate Construct
Journal of Spinal Disorders & Techniques, 2007Two common justifications for orienting cervical screws in an angled direction is to increase pull-out strength and to allow use of longer screws. This concept is widely taught and has guided implant design. Fixed versus variable angle systems may offer strength advantages.

Fibers and Polymers, 2011
The aim of this study was to understand the effects of softening treatment on pull-out properties of plain, ribs and satin fabrics. Polyester woven fabrics were used to conduct the pull-out tests. Data generated from these tests included pullout force, crimp extension and fabric displacement. A developed yarn pull-out fixture was used to perform single
