  3. The fem results indicated that as to the rough surfaces in sliding contact, the value of the contact pressure was very high which coursed a high value of the heat flow rate, meanwhile the sliding time was not enough for the frictional heat to transfer, thus the highest value of the body temperature occurred just on the sliding surfaces, which possessed a sharp thermal gradient in direction perpendicular to the sliding surface. so the great thermal stress was caused just by the sharp gradient and the thermal elastic distortion with which the contact pressure changed occurred simultaneously, thus this change of the contact pressure would affect the temperature distribution in return

    對于相對滑動的粗糙表面，因實際接觸面積小而導致接觸壓力很大，這樣使得熱流密度會很大，同時由於滑動時間很短，熱來不及傳導，最高溫度發生在摩擦表面，在垂直於摩擦面的方向有很大的溫度梯度，使得熱應力很大，且最大應力發生在表面，同時產生熱彈性變形，這種變形使得接觸區域內的壓力分佈發生變化，這種變化又反過來影響了接觸區域的溫度分佈。
