Analytical model of temporary gunshot cavity shape
Języki publikacji
Abstrakty
W prezentowanej pracy podjęto próbę analitycznego opisu kształtu chwilowej pulsującej jamy postrzałowej. Tkanki żywego organizmu aproksymowane są cieczą nieściśliwą. Określono analitycznie postać toru wnikania nieodkształconego pocisku w ciecz nieściśliwą. Kształt chwilowej jamy postrzałowej określa się za pomocą obwiedni rodziny pulsujących kulistych pęcherzyków gazowych ze środkami położonymi na torze wnikającego pocisku. Uzyskany w ten sposób kształt chwilowej jamy postrzałowej dość dobrze aproksymuje dane eksperymentalne.
The analytical mathod, describing the shape of the temporary pulsating gunshot cavity, has been presented in this paper. A non-viscous incompressible liquid approximates the tissues of the living organism. The simple algebraic formula, determinig the trajectory of the rigid projectile penetrating into incompressible liquid, has been derived. The shape of the temporary gunshot cavity is determined with the aid of envelope curve of the expanding family bubbles. The symmetry centers of the bubbles are placed along of the projectile trajectory. The results of the theoretical analysis, presented in this paper, are compatible with experimental data.
