Crack Initiation under Cyclic Compression冯美斌,陈新增,何家文摘 要:<正> The crack initiation behaviour under cycliccompression foy the notched specimen wasinvestigated. It has been found that the cyclesfor crack initiation increase with the increaseof compressive mean stress, and the decreaseof stress amplitude. The stress amplitude playsa more important role......
