“…These studies were confirmed by later investigations [12][13][14][15][16][17][18]. Very high interface temperatures [19] occur at the critical hot spots, resulting in microstructural transformations (martensite formation) [1,16,[19][20][21][22][23]. The martensite formation causes an increase in the volume and local thickening of the steel plates [2,23,24].…”

“…A variety of suggestions have been offered in the literature. Given the continuous differences in the thickness of the steel plate, Fieldhouse [22] suggested the use of friction materials with a low Young's modulus so that the unevenness of pressure can be compensated. In addition, a uniform mass distribution is recommended so that the heat distribution is homogeneous [22].…”

“…Diese Beobachtungen wurden in späteren Arbeiten bestätigt [3][4][5][6][7][8][9][10][11]. An den kritischen Hot Spots treten sehr hohe Oberflächentemperaturen [12] auf, was zu Gefügeumwandlungen (Martensitbildung) führt [1,2,5,[12][13][14][15][16]. Durch Martensitbildung kommt es zu einer Volumenzunahme und zur lokalen Verdickung der Stahllamellen [1,16,17].…”

“…Zur Vermeidung von Hot Spots schlägt Fieldhouse [13] aufgrund der immer vorhandenen Dickenunterschiede der Stahllamelle die Verwendung von Reibmaterialien mit einem niedrigen Elastizitätsmodul vor, so dass die Pressungsunterschiede ausgeglichen werden können. Zagrodzkis [24] Simulationsergebnisse zeigen, dass eine Verringerung der Dicke der Stahlscheibe die thermoelastische Stabilität deutlich verbessern kann.…”
