Ferritic ductile irons were joined  by cold arc welding method by using the nickel base  electrode. In experimental part of the study,  firstly, mechanical and metallographical properties  of the welded specimens were identified. Then, J- Integral toughness values were determined by  fracture toughness tests for different crack  locations including base metal, heat affected zones  and weld metal. In numerical part of the study,  finite element analyses were conducted by fixing 3- D models precracked on different locations. After  stress ¿ strain analyses, stress triaxiality and  plastic deformation characteristics around crack  tip were determined for each crack locations and  different crack sizes. It was found that stress  triaxiality and plastic strain values increase with  growing crack length. Different regions with  different strength levels, affect the extension of  plastic deformation in the models. Hindrance on the  extension of plastic deformation at HAZ and  diffusion line causes extra increase in stress  triaxiality at crack tip.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783838357782\"\u003e\u003ch3\u003eExperimental and Theoretical Study\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783838357782","offer_id":39499069751389,"sku":"9783838357782","price":59.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/2c40b867-7f86-4127-863a-a2200e2f666f.jpg?v=1770705594","url":"https:\/\/shop.autorenwelt.de\/products\/fracture-behavior-of-welded-ductile-iron-von-hakan-cetinel","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
