Crack propagation through the interface between two polymer materials
Original language description
The existence of step change of the material properties influences stress distribution near the crack tip and also influences crack propagation through the interface. This work is focused on stability conditions of the crack perpendicular to the interface between two polymer materials and discusses estimation of the critical distance d used in stability criteria for crack touching the interface. The stability condition of the crack penetrating through the interface between two polymer materials was studied and numerically investigated. The resultant values of critical load were determined by stability criterion based on strain energy density factor for different elastic mismatch of the materials considered and for different values of critical distanced. The results of this study can lead to better lifetime prediction and safer design of layered structures.
