Correlation of Fracture Toughness With Charpy Impact Energy for Low Alloy, Structural Steel Welds

Abstract: Correlations between Charpy impact energy and fracture toughness values have continuously been developed because of their applicability in structural integrity assessment methodologies. This also applies to the integrity analysis of welded joints, which represent material discontinuities and potential failure locus in structures. Therefore, in effective FFS methodology applications, the fracture toughness of welded joints located in critical regions should be accurately estimated. This work addresses an estima… Show more

“…ble failure locus in the structures. They estimated the fracture toughness of steel joints using Charpy impact tests [8][9][10]. Similarly, Zhou and colleagues used Charpy impact specimens to obtain fracture toughness and thus minimum design metal temperature of irradiated steels preferred in the nuclear industry [11].…”

“…Além da caracterização da composição química, propriedades mecânicas e tratamento estatísticos dos valores de tenacidade à fratura frágil por clivagem da junta soldada SMAW, dados adicionais da junta FCAW obtidos por BIANCHI et al [58] e metal de base (ASTM A572 Gr. 50) oriundos do trabalho de Barbosa e Ruggieri [59] são incorporados no trabalho a fim de se realizar uma análise complementar.…”

“…Os resultados obtidos pelos ensaios de tenacidade ao entalhe em V por impacto Charpy-V para o metal de base e suas juntas soldadas (metais de solda SMAW, SMAW-PWHT e FCAW [58], e metal de base [59])vide Figuras 4.2,4.5são apresentados nesta seção. Em seguida, a determinação dos coeficientes da curva de ajuste da função tangente hiperbólica é feita a partir da manipulação dos valores de energia Charpy-V ( 𝐸 𝐶𝑉𝑁 ) provenientes de cada material, seguindo o procedimento descrito na seção 3.5.2.…”
