Aliabadi, M. H. (ed.) et al., Static and dynamic fracture mechanics. Southampton: Computational Mechanics Publications. 177-234 (1994).

We begin with the basis of quasi-static dynamic fracture mechanics (section 1), then it is followed by the construction of analytical and numerical solutions (finite element method), determination of stress intensity factors in different problems for bodies with cracks subjected to steady-state vibrations (sections 1 and 2). Section 3 is dedicated to the determination of dynamic stress intensity factors in limited and unlimited bodies in the case of impact loading. Under investigation is the influence of microcracks on the propagation of arterial cracks.

The two following sections treat a new field of fracture mechanics, the influence of electromagnetic fields on cracks propagation. It is noted that a deceleration (treatment) of cracks with the help of strong electromagnetic fields is possible. Finally, section 6 compares theoretical and experimental results in dynamic fracture mechanics that lead to the necessity of construction of new models for an adequate description of essentially dynamic processes.

For the entire collection see [Zbl 0801.00016].
