| Abstract: | The experimental technique takinq measure of the deformation of pressure vesselscontaining the crack is presented by use of moire interferometry method.The field of the elasto plastic strain,the size of the plastic zone and the COD date around the crack tip are determinedby the method.The experimental results agree well with those calculated by the theory formulation and the four kinds of COD design curves.The conclusions are that this experimental methodis advisable and that the experimental results are reliable. |
