| Abstract: | The essence definition of thin wall part is analysesed. The criterion of thin wall part is introduced. The research is performed theoretically, and the limits of tradition criterion of thin wall part are pointed out. The existence instantaneous of thin wall part is demonstrated theoretically, the instantaneous time for the object turning into the thin wall part is figured out and the corresponding conditions are also given. This result is benefits to scientifical criterion of thin wall part, expands the application of thin wall part and perfects defect of traditional criterion of thin wall part. |
