    AnnotationThe critical configuration of a crack arrested at a bimaterial interface is estimated. The stability of the crack in the soft material, whose front is situated at the interface between soft and stiff materials and who grows continuously sideways, is analyzed. A laminate with an ABAB structure containing a surface crack is considered in this study. The effective value of the stress intensity factor for the central segment of the crack front lying at the material interface is calculated for various geometrical and material configurations. Comparing the effective value of the factor with the corresponding threshold values, the stability of the configuration studied can be assessed. It is found that a 3D solution for estimating the effective stress intensity factor is necessary to describe the crack behavior at the interface even for a relatively shallow crack. The results presented can be helpful for the inspection of lamellar structures.
