These are the P-wave (pressure wave or primary wave) that shows up first in an accelerometer trace and the S-wave (shear wave or secondary wave) which shows up laterThese two definitions are equivalent if the crack blunts in a semicircleA good book for the basics is "Wave Propagation in Elastic Solids" by Jan D Log in or register to post comments As far as I know, it requires calculation of energy release rate of a virtual extension of the current crack in various directions, which may not be convenient for numerical implementation

Best, RH Log in or register to post comments According to the pipeline application there is a trend to consider a range of critical CTOD values between 0.1-0.25 mm [37,64,69,86] Log in or register to post comments Figure 1API X80 steel two-passes FSW joint, SE(B) specimen submitted to CTOD test at 25 C, 15 mm thicknessDid you know the paper or the other source say about the sinificant effect of reflected stress wave on the local crack-tip fileds? Please help me!! Thanks and Regards,, Chau Log in or register to post comments The number of cycles required to perform the fatigue precracking depends on the temperature, specimen size and geometry, material, residual stresses, machined notch radius, load ratio (R=Pmin/Pmax) and stress-intensity factor (KIC)FEDELINSKI* AND MIn an internal report [39], SE(B) square specimens of 9Ni delivered reliable information 515b946325
