| Abstract: | With the theory of wavefront interference, formulas which represent the displacement and strain in the surface of cylindrical shell evaluated by SFMI have been obtained.The inference of rigid body displacement to the measured strain and displacement are analysed. Suggestions about the method of SFMI applied to pressure vessels and pipeline are made. |
