| Abstract: | The system of dynamic strain's measure and calculating the result of measured strain by extrapolation are introduced.On the basis of lots of test,referenced the theory of elastic mechanics,the maximum dynamic strain and the maximum principal stress of the point measured can be calculated.The step of the extrapolation of the test is described in detail. The extrapolation of the test had the great use in the engineering. |
