Development of Mechanical Properties Database of A285 Steel for Structural Analysis of Waste Tanks

Abstract: A statistically-designed test matrix has been developed to govern test conditions for measurement of the fracture toughness properties of A285 carbon steel. The effects of several variables on ductile tearing were investigated. The results of initial J-Integral testing are presented along with preliminary observations and data analysis. These results will contribute to a database of J-resistance (J-R) curves, which will be used for flaw stability analyses in waste storage tanks constructed in the 1950s at the … Show more

“…A condição CF também apresenta separações, no caso, uma delaminação na região relativa a banda de segregação formada por fases com alta dureza. Duncan (2000) e Silva (1986), dentre outros, destacam que em amostras CTOD de aço obtido por laminação controlada, com microestrutura bandeada (perlita e ferrita) observa-se freqüentemente a ocorrência de separações ou delaminações nas bandas de perlita. Desenvolvemse fraturas de baixa energia, paralelas ao plano de laminação da chapa e perpendiculares ao plano de propagação da fratura principal, em corpos de prova com orientações longitudinal ou transversal.…”
