MODELLING  ANDDESIGN  OF  CONCRETE  AND  FERROCONCRETE  STRUCTURES  TO  RESIS  THIGH-SPEED  PROJECTILE  IMPACTS*

The paper suggests mathematical models of concrete and ferroconcrete behavior exposed to a shockwave loading. Model verification was provided by a comparison between mathematical modeling and experimental results on projectile force generated by steel bars and concrete and ferroconcrete plates. Computer simulation used to study the projectile impacts including those contained an explosive material has allowed to animate impacts at different angles crushing concrete and ferroconcrete plates (with spatial separation, sand-filled spacing, and others) which represented industrial constructions.

* This work was financially supported by grant N 12-01-00227а from the Russian Foundation for Basic Research.

Keywords: concrete; ferroconcrete; shock-wave exposure; disintegration.
