Cracks approaching the interfaces in the core of a sandwich construction are investigated. For pure tension, pure bending and shear the cracks are shown to go through a regime where a maximum stress intensity factor is attained before the crack tips enter the interface. The cracks are analyzed within the framework of analytical elasticity. The analysis methods are outlined, and the solution is established in an object oriented programming environment, which allows solutions to be obtained for a wide variety of parameters. Results are given in terms of a case study pertaining to sandwich constructions with aluminum faces and two different foamed PVC core, as well as in more generalized terms.
