Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Abstract In this study, a model of a quick-coupler device is investigated and presented within simulation modeling software. A method is presented that enables the design and construction of a simulation model of a quick-release device as an alternative to physical modeling for further investigation. The predicted service life of the tested quick-coupler model is estimated based on the S-N curve (fatigue curve). The S-N curve illustrates the relationship between stress amplitude and the number of cycles to material failure.
