Book Description
Within the limit of relatively short arrested crack, static approximation by applying linear fracture mechanics has yielded useful results for theoretical interpretation and practical application of currently used brittle fracture propagation arrest test (the concept of arrest toughness). But later experimental investigations using very wide specimens (1300 to 2500-mm-wide plates) have revealed that this simple interpretation fails to have a consistency with the case of a long arrested crack. For the inadequacy of static approximation based on arrest toughness concept, the concept of an effective stress intensity factor has been introduced from a practical point of view without a clear quantitative explanation for it. In search of a more relevant theory for fast crack propagation and to see how the neglect of dynamic aspects affects the interpretation of unstable crack propagation arrest test and philosophy of crack arrest design, a dynamic fracture mechanics analysis was made with the use of the finite-difference method to solve the equation of motion for the two-dimensional elastic problem.

Book Description
The proceedings of a seminar held at TWI in September, 1995, focusing on crack arrest philosophy which aknowledges that a brittle crack is arrested when it emerges from the critical region. Papers from prestigious researchers presented a critique and assessment of the theory and its application under: Introduction to crack arrest concepts; Recent trends in crack arrest research; Application of crack arrest concepts.
