Saturation ratio influence on perforation and penetration of concrete subjected to missile impact: a DEM approach

Résumé

Concrete structures are widely used as shielding barriers to protect sensitive infrastructures. Possible accidental conditions such as aircraft impacts on nuclear containment have led to an increasing demand for advanced design of concrete structures under extreme loading. Several studies have shown that the presence of free water in concrete significantly affects its response when subjected to static loading with high mean stresses or dynamic loading with high strain rates. Therefore, the aim of this paper is to investigate the influence of the saturation ratio on perforation and penetration of concrete. To achieve this purpose, the study will simulate the impact of ogive-nosed steel projectile on three plain concrete targets, passively confined by means of steel jackets surrounding the cylindrical specimens. Keywords Discrete element model • Impact • Concrete • Water saturation ratio • Strain rate effect
