| Abstract: | Two series of Al-Ti metals sheets from discard airplane parts and self made material were tested on normal mechanics and fracture mechanics. The KR curves were obtained according to test standard. By flexibility and K calculations KRi and aiwere measured separately and Kc was determined. Comparing the data of two series sheets the performances are very similar the new sheet was qualified to meet the property requirements of imported sheet. |
