Inhomogeneous Problems in Elasticity or Heat Conduction

N. LOUAT1 has recently described a method of solving two-dimensional problems in elasticity by the replacement of free surfaces by two mutually independent arrays of edge dislocations chosen so as to produce zero stress at each free surface. M. A. Jaswon2 has described a similar procedure in which prescribed boundary displacements may be achieved by means of boundary distributions of point forces chosen to satisfy a set of Fredholm integral equations. The attraction of each method lies in the fact that the effect of a point force within an infinite medium may be calculated from a simple formula. Furthermore, the use of digital computer techniques allows the superposition of a large number of such forces.
