N2 - Plenary Lecture for the ICF-13. The paper is presenting structural-temporal approach for analysis of multiscale nature of dynamic brittle fracture. Typical examples illustrating typical dynamic effects inherent in dynamic fracture process are analyzed. A unified interpretation for fracture of solids utilizing structural-temporal approach based on the concept of the fracture incubation time is proposed. Corresponding generalized model accounting for fracture scale level is also presented. Notion of spatial-temporal cell for different scale levels is introduced. Two characteristic linear sizes specifying lower and upper boundaries of the scale level should be put in consideration in order to determinate correct experiments and the admissible characteristic size of the test specimen at a given scale level. Knowledge of both static and dynamic properties of the fracture process is principally important for this specification. It is shown that interconnections of fracture parameters of a given scale level with par
