Abstract
The proposed model formulation for brittle crack propagation/arrest behaviors in a steel plate has been validated by comparing with experiments of temperature gradient and duplex crack arrest tests. The proposed model formulation successfully predicted the experimental results, such as (1) a deviation from the empirical knowledge in the relationship between arrest toughness and temperature evaluated by the temperature gradient tests, and (2) a transition region of the crack arrest behavior evaluated by the duplex tests. The results consequently showed a possible solution to “the long crack problem”, which was not solved in the past studies.
