Research on the design and performance of drill pipe joints based on fracture mechanics methods.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
In actual drilling operations, fatigue failure of drill pipe joints primarily occurs at the threaded connections, significantly increasing drilling costs. Given the severe vibrations and abnormal wear experienced by drill pipes under complex working conditions, a three-dimensional finite element model of drill pipe joints was developed. This model is based on fracture mechanics theory, the principle of virtual work, the Von Mises yield criterion, and contact nonlinear theory, while also incorporating the influence of thread taper angles. By evaluating both straight and tapered threads with varying tooth profile angles, optimal structural parameters were determined. The results demonstrate that a 45-degree tooth profile angle represents the optimal configuration, meeting the fundamental requirements for water exploration in coal mines.
