碩士 === 淡江大學 === 機械工程學系 === 84 === By applying the boundary condition theorem , and the general rule of signvariation and necessary number of terms in the image method, the Green-Shaw,function for quarter-space solid, with the Green''s formula in integral formthe Papkovitch-Nunber-Boussinesq functions and the analytical solutionsof concentrated tangential forces acting on the surface of quarter-spacesolid were derived . By comparing the displacement and stress distributionof concentrated tangential forces acting on the surface of quarter- spacesolid with the displacement and stress distribution of conterated trangentialforces acting on the surface of halfr- space solid , we find that the valuesof the quarter-space solid is larger than the values of the half-spacesolid . The reason may be due to the the distribution of the material isnot equal . The displacement and stress distributions of quarter-space solidwere found to be very distributed and matching the physical meaning . Fromthe results of investingation in thesis , the reliability of the Green-Shawfunctions in solving practical engineering problems may be emphasized.
