Dynamic fracture testing of welding part of nuclear piping by using normalization method

In this study, we obtained two fracture resistance curves from static test of welding part of nuclear piping both by unloading compliance and normalization method. The two curves were almost same each other, so the adaptability of the normalization method has been proved. We conducted a dynamic fracture resistance test for the same material. The fracture resistance curve from the dynamic test was obtained by normalization method and compared to that or the static test result
