Strengthening Characteristics of Low Amplitude Loading for Different Specimens
摘要
Abstract
Using auto parts and standard material specimens, the strengthening characteristics of low amplitude loading was investigated. The results showed that the strengthening characteristics of low amplitude loading were greatly affected by the test specimens. For auto parts, there were obvious regions of strengthening cycles and strengthening loads, their strengthening conditions were easy to satisfy. Whereas the strengthening conditions of standard material specimens were strict, the strengthening loading should be matched with strengthening cycle which was higher than that of standard material specimen. The reasons of different strengthening conditions for these two types of specimens were primarily analyzed.关键词
