When a point of the component is subjected to a sufficiently large disturbance stress, a crack is formed after a sufficient number of cycles, and this phenomenon is called fatigue. Fatigue fracture is the main cause of failure of engineering structures and components. In the current application and research, there are four main types of fatigue testing methods: 1. Nominal stress and strain method; 2. Local stress and strain method; 3. Energy method; 4. Fracture mechanics method. This article briefly introduces the four types of methods and their applications. 1. Nominal stress method The nominal stress method is a method of applying a rated stress test to a standard component,…<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[79],"tags":[],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts\/1690"}],"collection":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/comments?post=1690"}],"version-history":[{"count":0,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/posts\/1690\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/media?parent=1690"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/categories?post=1690"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.meetyoucarbide.com\/ja\/wp-json\/wp\/v2\/tags?post=1690"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
