METHOD FOR ANALYZING A SEPARATION IN A DEFORMABLE STRUCTURE |
摘要 |
A deformable structure is subjected to a plurality of reduced pressures, causing a bulge in the surface of the deformable structure above a separation in the deformable structure. The cross-sectional area of the bulge is measured for each reduced pressure in a plane parallel to the surface of the deformable structure. When the cross-sectiona l area of the bulge does not increase with a reduction in the pressure, the cross-sectional area of the bulge approximates the area of the separation. The depth of the separation is calculated using the change in cross-sectional area of the bulge per change in pressure.
