Influence of contact compliance on dynamic stress intensity factor variation during an impact test
Source abstract
Abstract
Influence of the contact compliance on magnitude of oscillations of dynamic stress intensity factor (DSIF) during an impact test has been investigated numerically. It has been shown that although this magnitude is mainly determined by geometry of the specimen (namely, by combination of its relative length and relative crack depth), changes in contact stiffness affect the magnitude as well. For the range of specimen configurations and contact stiffnesses considered, the smallest DSIF oscillations were obtained for the impact specimen with relative length 5.5 and relative crack length 0.3.
