| Abstract: | This paper analysis the characteristics of hydraulic expanding froma- tion and gives out the true stress-strain curves of five kinds of mater- ials.Three calculating methoods were provided and discussed by using hydraulic expanding formation experiment to measuren value;the optimum interval of value fetch of calculating n value was tested and studied by using experimental data,too. |
