| Consider a space containing a hole of radius R and an crack of length A. Establish the Cartesian coordinate systems at the circular inclusion and the interfacial crack respectively. Let the coordinate origins be at a distance h below the surface. The distance is d between the hole and the crack. The governing equation can be written in the following simplify form if wave impacts on the space at a certain angle. |
