Measurement of Interface Fracture Toughness of Sandwich Structures

Østergaard, Rasmus C. / Sørensen, Bent F.

Abstract Sandwiches are analyzed by the application of linear elastic fracture mechanics. An expression for the energy release rate is found by analytical evaluation of the J-integral. Also, a method for determining the mode mixity is described and applied. The theory presented is applied to a test method and the fracture toughness of two sandwiches are measured as function of the mode mixity.
