Abstract: On the basis of Stiffness Matrix Method (SMM), a boundary element method to 2-D layered media (BEMLM) is developed in this paper to the crack analysis problems in layered elastic media By way of introducing additional interfaces together with its dislocation connecting conditions, SMM can be modified to include unit concentrated dislocations in its basic stiffness relations, which can be served as fundamental solutions to the layered media These fundamental solutions are given either in explicit form as...
