摘要：

The study presents the results of investigation for different aluminum alloys. Small samples of these materials were subjected to static and dynamic tension. A numerical analysis using an incubation time fracture criterion has been carried out. For each material a set of fixed constants were obtained that allows determine the dependencies of the tensile strength of material in a wide range loading conditions. (C) 2018 The Authors.
