Abstract
The author and his group have developed numerous computational methods and
experimental measurements for fracture studies, especially for dynamic fracture
studies. In the first part of this paper, the concepts of the hybrid experimental-
numerical methods are explained. On the basis of these concepts, various hybrid
experimental-numerical methods used in dynamic fracture mechanics are
classified. The key technologies developed by the authors for the studies of
dynamic fracture are uitrahigh-speed photography to visualize various dynamic
fracture phenomena and various moving finite element methods together with
the path independent dynamic J integral. In the last part, features of the hybrid
methods are presented with pertinent results obtained by our recent studies.
