Werkstoffanstrengung im Hertz'schen Kontakt infolge Last‐ und Eigenspannungen

Abstract

Material Stressing in a Hertzian Contact – Influence of Load and Internal Stresses For the analysis of the material stressing in a Hertzian Contact due to elliptically distributed normal load it is sufficient to calculate the stresses at z ≥ 0, × = y = 0. At this point the maximum stress occurs in the contact surface as well as in the stressed volume. From the center to the rim of the contact the stress decreases. In the case of residual stresses in the material it is necessary to calculate the resulting stresses in the entire contact area. The superposition of stresses due to load and internal stresses can cause stressings of the material with a maximum in the region of the rim of the contact area. The calculation of the conditions in the center alone can lead to misinterpretations.

“…Das Thema Oberflachenermudung wird seit etwa 14 Jahren bearbeitet. Die Ergebnisse der theoretischen und experimentellen Untersuchungen sind in zahlreichen Veroffentlichungen [ [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] Gerade aus Abb. 6 geht hervor, wie wichtig die Betrachtung der Verhaltnisse in unmittelbarer Nahe der Oberflache ist.…”
