%X This paper presents an approach to modeling a general system containing multiple interacting cracks and voids in a plane elastic media. By extending Bueckner's principle suited for a crack to a general system containing multiple interacting cracks and voids, the original problem is divided into a homogeneous problem (the one without cracks and voids) subjected to remote loads and a multiple void-crack problem in an unloaded body with applied tractions on the surfaces of cracks and voids. Thus, the results in terms of stress intensity factors (SIFs) can be obtained by considering the latter problem, which is analyzed easily by means of the Hybrid Displacement Discontinuity Method (HDDM) proposed recently by the author. Many test examples are included to illustrate that the method is very simple and effective for analyzing arbitrary multiple cracks and voids in a plane elastic media.
