Both experimental and numerical methods\u003c\/p\u003e\u003cp\u003ehave been adapted in order to predict the lifetimes of dissimilarly welded superheater tubing\u003c\/p\u003e\u003cp\u003ein power plants. The fatigue behavior and lifetime predictions of such components\u003c\/p\u003e\u003cp\u003eare complicated at high temperatures since a complex interaction between thermally activated,\u003c\/p\u003e\u003cp\u003etime-dependent processes are involved. At the same time, components that operate\u003c\/p\u003e\u003cp\u003eat elevated temperatures are often subjected to transient temperatures due to start-up and\u003c\/p\u003e\u003cp\u003eshut-down where thermally induced cyclic stresses can occur. The superposition of thermal\u003c\/p\u003e\u003cp\u003etransients with mechanical load cycles along with unequal heating of parts of a component\u003c\/p\u003e\u003cp\u003eresult in a complex evolution of damage, leading to TMF failure of the component. To add\u003c\/p\u003e\u003cp\u003eto the complexity, the degradation mechanisms relevant to welded power plant components\u003c\/p\u003e\u003cp\u003ecan be accelerated by the presence of residual stresses.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783656268895\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9783656268895","offer_id":39446171844701,"sku":"9783656268895","price":47.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/e2c8c1c8-713c-4d97-97c5-e704b00fd166.jpg?v=1781760288","url":"https:\/\/shop.autorenwelt.de\/products\/a-computational-approach-to-thermomechanical-fatigue-life-predictions-of-dissimilarly-welded-superheater-tubes-von-ram-kumar-krishnasamy","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
