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

Quasi-static problems with respect to the stress-strain state and a class of problems with respect to forced vibrations acting in plain and spatial nodes of a high-class mechanism with elastic links are considered, taking into account the model of friction forces in kinematic pairs under the action of vertical and horizontal concentrated forces in kinematic pairs. The developed algorithms of solving quasi-static problems by the finite element method for the entire system of the elastic mechanism with the friction force in kinematic pairs are presented; the basic resolving equilibrium equations for the entire system are drawn up without and taking into account friction forces. The basic relations of the finite element method for plain and spatial nodes of high-class elastic mechanisms with the friction force in kinematic pairs under dynamic loading are presented.
