Finite element simulation of fretting wear and fatigue in thin steel wires

A combined wear-fatigue design methodology for fretting in the pressure armour layer of flexible marine risers

“…The universal slopes method [25,26] has been used to estimate the Basquin constants (σ'f and b) for the computational fatigue model (see Table 3). The universal slopes method, in which the slopes of the plastic and elastic lines are universalised as -0.6 and -0.12 respectively for all materials, has been widely used, [26 -27] for example.…”

“…The spacing for the MPM is determined from the initial location of each element centroid for the unmodified mesh, following [26].…”

Reliability Research Reviewed of Automobile Seat Angle-Adjuster

“…Through establishing mathematical model conforming to the actual working condition, carrying out the optimization design of the product under the theoretical guidance, so as to maximum enhance regulating function on the basis of satisfying its selflocking performance. Double linkage seat angle-adjuster for around two sets of adjustment locking mechanism in a set of institutions under the control action at the same time, the lock at the same time, the locking strength is higher and it is applicable to all kinds of buses coach passenger [14]. Due to the safety of car seat, comfort and durability depends largely on the quality and technology level of seat angle-adjuster, so the research on automotive seat angle-adjuster structure optimization and reliability is of great significance [15].…”

Methodology for reliability assessment of steel wire ropes under fretting fatigue conditions

“…In this respect, numerous research works on the fatigue properties of drawn steel wires have been published [24][25][26]. The mechanism of fretting fatigue in spiral stranded wires has also received much attention [27,28]. Microstructural changes derived from the drawing operation and their mechanisms in improving the toughness of wires were addressed [29,30].…”
