Wellen- und Bruchphänomene in Keramik
Abstract
Impact experiments against glass and alumina are performed to study wave and fracture behaviour under dynamical loading. It has been found that alumina behaves quite different than glass. As experienced from fracture mechanical viewpoint, glass showed a terminal crack velocity of about 1500 m/s. No distinct terminal crack velocity could be found with alumina. Although for certain loading conditions the crack velocity seems to be terminated, different terminal crack velocities are measured for different impact situations.
