Schindler, H. J. An engineering concept to account for crack-tip constraints. (English) Zbl 1150.74594 Facta Univ., Ser. Mech. Autom. Control Robot. 3, No. 13, 613-622 (2003). A promising possibility is suggested, where a new constraint parameter \(G\) is introduced. It has two main advantages: it can be obtained easier than the commonly used \(Q\)-parameter, and it is related to the fracture toughness parameters by closed-form equations.
