Abstract:	Based on Eringen's Micropolar Elasticity Theory, a two-dimensional Boundary Element (BEM) formulation is derived and the corresponding computer programs are developed to solve the two-dimensional stress concentration problems of micropolar elastic material with arbitrary non-smooth surfaces. The new 2-D BEM formulation is first applied to solve the stress concentration around a hole in a plate under tension, and shown to be in excellent agreement with existing analytical solutions. Next, the new BEM formulation is applied to solve, for the first time, the stress concentration around a semicircular edge notch in a plate under tension. The effects of coupling number, characteristic length and radius/width ratio on the micropolar effects are derived, and the important new findings are summarized. (C) 1997 by John Wiley & Sons, Ltd.
