Abstract:
The model of brittle fracture of thin-wall structures developed earlier by
the authors is used to compare the protective arms of ancient soldiers on the
basis of numerical solution of linear and nonlinear solid mechanics problems.
Comparison of functional properties of protective arms is carried out by the
comparison of fracture zones of the armors made of bronze or iron plates.
Dynamic deformation of “armor-human body” system under the impact of an arrow
released from a bow is modeled by the concentrated mass (equal to the mass of
the arrow tip) with a specified initial velocity. Numerical solutions of
the problems were obtained with the PIONER computer code. Some quantitative
characteristics of protective properties for bronze and iron plates are
presented.
Keywords:method of mathematical modeling, mechanics of deformable solids, dynamic deformation, brittle fracture models.
