Abstract

This study offers a new constitutive and failure model for the concrete which covers a wide range of the impact phenomena. The authors extended the static non-uniform hardening plasticity model developed by Han and Chen, mainly to the high strain rate region. The model, called 'Dynamic Drucker-Prager CAP Model', was implemented in a hydrocode AUTODYN™ through the subroutines which are open to the user. Then, a number of numerical analyses were carried out by using the material model, which simulate the impact tests on reinforced concrete structures by the aircraft. In the experiment, the engine was modeled by a rigid or a d
