| Abstract: | The theory of total evaluation of difficult system on Ti shape is proposed. The evaluated equation on fuzzy control is introduced, the system of evaluated degree is built. The total evaluated equation on the yield and fracture of drawing shape of TC1. TC2 is showed, using different yield criteria. The special goal specimen of TC2 is combined with the special predict results. The total evaluation method takes an important part in speeding national self-made of plane. |
