Abstract

This paper describes work performed with the RHT concrete model, which shows promising behaviour for penetration/perforation simulations in concrete. The three dimensional simulations, using both Lagrange and SPH formulations, consider cases with varying impact conditions and target configurations. The simulations that consider normal impact conditions are compared with earlier benchmark tests. Keywords: numerical simulation, concrete penetration, RHT model, SPH, smooth particle hydrodynamics, meshless. 1 Introduction It is necessary to predict penetration depths in concrete targets to determine the vulnerability of underground structures. Several empirical and numerical tools have been developed to predict penetration depths of projectiles in concrete. Previously presented 2D simulations by Hansson [1] are extended
