Finite element simulations in ABAQUS as well as beam theory models are developed to study the role of material properties and traction separation relations in determining the interface of crack propagation. For mode-independent transfer of 2D materials, the results indicate that interface selection is strength driven. We explore the effect of shear to understand the shift from strength driven to fracture energy driven fracture under mixed-mode conditions. In the case of thin films (thinner than the substrates), simulations indicate a shift from fracture energy driven behavior to interface strength driven mechanics based on initial crack lengths, elastic modulus of the thin film as well as its thickness.
