“…Although many materials seem to behave accordingly, the basic mechanism which causes this softening is still unresolved. Recent work on the subject is focused on the basic physics behind this process, as can be found in [2][3][4][5], for example. These works emphasize the link between adiabatic shearing and ductile fracture by the coalescence of microvoids, since the shear zones act as precursor sites for eventual failure by cracks (see [2]).…”

These works emphasize the link between adiabatic shearing and ductile fracture by the coalescence of microvoids, since the shear zones act as precursor sites for eventual failure by cracks (see [2]). GIOVANOLA [3,4] conducted a careful experimental study on 4340 steel specimens, in order to follow the evolution of strain localization and failure which he finds to proceed in two stages.…”

“…Доказательством высокой температуры внутри полос адиабатического сдвига авторы [15] считают наличие пор (полости округлой формы). Заметим, что в сжатом материале поры или трещины возникать не могут из-за стесненности, сжатие как раз используется для залечи-вания несплошностей.…”

“…Заметим, что в сжатом материале поры или трещины возникать не могут из-за стесненности, сжатие как раз используется для залечи-вания несплошностей. Другим доказательством высокой температуры внутри полосы сдвига авторы [15] считают наличие ступенек на поверхности кратера, от которых идут узкие полосы сдвига. При ударе массивного шара в экспериментах [15] причиной образования ступенек на поверхности кратера является периодический выход ударной волны на свободную поверхность перед грани-цей контакта, когда скорость перемещения последней становится дозвуковой.…”
