To address the susceptibility of premium threaded connections in deepwater gas production strings to fretting wear and seal failure under long-term cyclic loading, a numerical simulation method for fretting wear was developed based on the Archard wear model. A UMESHMOTION wear subroutine was written in Fortran and comb...
Surface indentations of bearing raceway, caused by contamination particles, are a major source of surface-initiated rolling contact fatigue in heavy-industry applications. Material pile-up (shoulders) formed around the indent are the primary contributors to local pressure increase, lubricant film disruption, tensile re...
The paper presents the results of a computational and experimental study of a sliding bearing unit operating under high dynamic and radial loads as part of a compact roller test bench for heavy-duty vehicles weighing up to 20 t. A shaft and roller design based on a multilayer composite-metal structure has been develope...
In order to reduce the failure of thread joint of drill pipe, its connection performance and sealing performance need to be improved. Based on the mechanical analysis of the joint and yield criterion of von Mises, the three-dimensional finite element model of the single shoulder and double shoulder with NC38 thread pro...
The increasing use of multi-material structures in body-in-white applications has increased the importance of mechanical joining technologies such as self-piercing riveting (SPR). Since formed sheet metal components often exhibit local plastic pre-deformation in the joining zone, the effect of this pre-deformation on j...
In the subsequent backfilling mining method, the composite structure formed by the ore pillar and the backfill is the key element in ensuring the stability of the working face. Its mechanical behaviour directly affects mining safety and ore recovery rates. In order to elucidate the mechanical response and failure mecha...
