| Abstract: | In this peper, the relahonship between nolnjnal fracture stress and initial cracklength of through-centre cracked LY12 plate specimens is established from fracture experimentalresults. Plate specimens are subjected to Septic and dynamic tensile loadings respectively. Therelations of some parameters in ststic and dynamic experiments are compered. |
