A METHOD FOR QUANTITATIVE INSPECTION OF COLD-EXPANDED FASTENER HOLES |
摘要 |
A method for inspecting a cold expanded fastener hole (1) in a structural part (2) to confirm that the hole has been expanded by a desired amount involves determining the degree to which the hole has been expanded as a function of the out-of-plane deformation in material surrounding an entrance or exit of the hole formed as a result of the cold expansion process. Out-of-plane deformation at either of the entrance or exit is compared to a model constructed from an array of experimentally or analytically determined out-of-plane deformation profiles for a hole with the same, or substantially the same dimensions subjected to varying degrees of cold expansion. The degree of expansion of the hole is derived based on this comparison. |
