- W2374231038 abstract "Instrumented impact tests are carried out using precrack Charpy specimens of typical pressure vessel steel Q345 R,the load-displacement curves are obtained.Based on the test data,the J-integral incremental equation procedure and Schindler method are used to estimate dynamic crack resistance curve of Q345 Rsteel under impact loading respectively.The results of them are compared and verified each other.After comparing the dynamic J-Rcurve with the qusi-static curve,it is found that the J-R curve under dynamic loading is always higher than that obtained under quasi-static loading.Further analyses of test data lead to an equation which quantitatively describes the relationship between Q345 R quasi-static and dynamic crack growth resistance curve.The equation may have important significance in engineering application." @default.
