Методом чисельного моделювання проведено оцінку впливу форми електрода-ударника на напружено-деформований стан пластини виготовленої з алюмінієвого сплаву АМг6 після їх ударної взаємодії на швидкості 10м/с. Описано особливості створення відповідних математичних моделей. Встановлено розміри зони пластичних деформацій. Визначено розподіл по товщині пластини значень компонент напружено-деформованого стану, а також глибини та ширини вм’ятини в пластині.

The influence of the shape of the electrode-indenter on the stress-strain state of the plate made of aluminum alloy AMg6 after their impact interaction at a speed of 10 m/s was evaluated using numerical modeling. Features of creating appropriate mathematical models are described. The dimensions of the zone of plastic deformations have been established. The distribution of the values of the components of the stress-strain state, as well as the depth and width of the dent in the plate, along the thickness of the plate was determined.
