摘要：This work presents a Boundary Element Method formulation for
modeling two-dimensional microstructures containing cylindrical voids
and inclusions. Inhomogeneities are modeled in an efficient way by using
a single specially developed element. Trigonometric functions are used as
a base for the element shape functions. A static condensation scheme is
performed on the system of equations to further improve the efficiency of the
formulation. The accuracy of the proposed method is illustrated with some
examples.
