- Abstract
- The fracture toughness of double edge notched tension (DENT) specimens of a low carbon steel sheet was evaluated using experimental and numerical methods. The concepts of critical J integral J(c) critical crack tip opening displacement delta(c), essential work of fracture w(e), and essential work of fracture and initiation w(e)(init) were compared. The numerical methods were based an finite strain, three-dimensional finite element simulations of the tensile straining of the DENT specimens. Good agreement was found between numerical and experimental J(c) values. Fair agreement was also found between J(c), and w(e)(init). The essential work of fracture w(e), was similar to 20% lower than J(c). This discrepancy is attributed to inaccuracy in the detection of clacking initiation. The Shih factor derived from the measured J(c) and delta(c) values closely corresponds with the plane stress prediction. MST/3935.
