YamashW ^Department of Mathematical Engineering, College of Industrial Technology, Nihon University, 1-2-1 Izumi-cho, Narashino-shi, Chiba-ken 275, Japan Department of Mechanical Engineering, Oyama National College of Technology, 771 Nakakuki, Oyama-shi, Tochigi-ken 323, Japan ABSTRACT The boundary element analysis of two-dimensional elastic body based on the micropolar theory which is known as one of the Cosserat continuum theory is discussed in this paper. The boundary integral equation and fundamental solutions in order to solve numerically such problems are derived. Not only the effect of couple stress for materials but also the applicability are examined through some numerical examples. INTRODUCTION Recently, it becomes indispensable to take into consideration of the influ- ence of microstructures of the industrial materials as a polycrystalline metal, granular material and fibrous body in
