An attempt is made to take into account the surface influence upon the mechanical energy of point defects and volume defects in an isotropic elastic solid. In addition the defect‐matrix modulus effect is also considered which is usually neglected. A theorem is investigated refering to the sign of interaction energy between defect and surface. An axisymmetric finite element program (FEM) is applied to carry out numerical calculations. The application of this method to probelms in structural physics (microphysics of solids) seems to be very useful.
