A general exact transformation of body-force volume integral in BEM for 2D anistropic elasticity

摘要

In a previous study (Zhang, Tan and Afagh, 1995), the present authors successfully transformed the body-force volume integrals in BEM for 2D anisotropic elasticity, to bound- ary ones. This restores the BEM as a truly boundary solution process for treating anisotropic bodies involving body forces. However, the formulation is valid only for problem domains Which are geometrically convex and simply connected. This Paper presents a general and exact transformation of the body- Force volume integrals in BEM to line integrals for 2D aniso- Tropic elasticity, in which the above-mentioned restriction on The geometry of the domain is eliminated. The successful imple- Mentation of the formulations is demonstrated by three practical Examples.
