“…Many of them recognize the problem of the estimation of the friction coefficient, however, they neglect it and consider the friction coefficient to be constant, taking the value of = 0.3-0.4 [1,5,7,10]. Kumar et al [16] was among the first to propose an experimental model for the estimation of the friction coefficient at FSW.…”

“…), and the temperature of workpieces increases, one can conclude that the mechanical energy delivered to the welding tool is significantly transformed into heat. The amount and intensity of heat generation during FSW is the topic of various researches [3][4][5][6][7][8][9][10], and this paper deals with parameters that influence heat generation during FSW.…”

“…Les modèles numériques par éléments finis utilisent principalement le référentiel lagrangien et donnent des résultats intéressants qui sont souvent très près des mesures expérimentales [8,11,12,19,21,37,41] pour le soudage par friction malaxage. Ils permettent de mieux comprendre les mécanismes physiques derrières le procédé qui influencent la fiabilité et la qualité des soudures réalisées avec cette technique.…”

No matter what kind of models are used for FSW thermal analysis, the heat generation rate is the major difficulty because of the unknown friction coefficient, which is affected by many factors.…”
