摘要
Bars cyclically loaded by opposite concentrated forces via rollers are appropriate test specimens for the determination of fatigue under contact loading. As practical applications of the proposed test, the contact strengths and numbers of cycles to failure under contact loading were determined for three Al2O3. In additional tests the residual strength after a pre-loading under contact loading conditions was determined in four-point bending tests. (C) 2002 Elsevier Science Ltd. All rights reserved.
