Abstract

A multiscale approach to the study of the plastic flow evolution pattern in the neck of high-strength structural steel and submicrocry stalline armco iron and titanium specimens is used to describe the physical nature underlying the difference in the fracture mechanisms between these materials. An important role of local regions of bulk tension in micropore and crack formation and subsequent fracture of the materials is demonstrated by experiments and numerical simulations.
