Abstract In this paper, some remarks for more efficient analysis of two-dimensional
elastostatic problems using the method of fundamental solutions are made. First, the effects
of the distance between pseudo and main boundaries on the solution are investigated and by
a numerical study a lower bound for the distance of each source point to the main boundary
is suggested. In some cases, the resulting system of equations becomes ill-conditioned for
which, the truncated singular value decomposition with a criterion based on the accuracy of
the imposition of boundary conditions is used. Moreover, a procedure for normalizing the
shear modulus is presented… More >
