| Abstract: | A new method of measuring damage variable D(E) was put forward, in which changing cross section specimen was used. The formulas for getting E and D(E) were derived in theory, and several factors which can affect the accuracy of the results were analysed.Finally, the whole method was tested in practical experiments.The results showed that it is feasible and effective.Especially,it made possible the study of the same damage process from different angles by contrast. |
