摘要
对贴片云纹干涉法在压力容器裂纹问题研究中的测试技术、数据处理作了探讨;运用波前干涉理论得到了贴片云纹于涉法求圆柱面的位移、应变公式;测得了压力容器轴向裂纹尖端位移场、应变场、K_?及COD。
In this paper, the experiment techniques and the data processing of
SFMI have been probed. With the theory of wavefront interference,
formulas which represent the displacement and strain in the surface of
the cylindrical shell evaluated by SFMI have been obtained. With the
improved method of SFMI, the displacement field, the strain field, K_I
and COD of the axial through crack tip of pressure vessel have been
measured.
