Abstract

In this paper two dimension (2D) asymmetrical numerical simulation analyses has been conducted on ABAQUS using dynamic Explicit analysis and Concrete damaged plasticity constitutive model. The simulation study was conducted for critical impact energy on thick concrete slabs impacted with ogive nose hard projectile diameter of 26.9mm and 76.2mm having CRH ratio 2.0 and 6.0. The limitations of concrete damaged plasticity model also have been analyzed. Furthermore, the simulation modeling was extending to achieve critical impact energy and residual impact energy for perforation of same thick concrete slab. In case of penetration, it was found that the simulation results are in close relation with experimental data. The limitation of Concrete damaged plasticity model found as that, during the impact analyses model does not allow the removal of elements. The extended simulation modeling for perforation shows encouraging results for critical impact energy and residual impact energy.
