In this paper, an Adaptive Smoothed Particle Hydrodynamics has been utilized in order to simulate the impact response of reinforced mortar beam subjected to low velocity impact loading. Drucker-Prager (DP) with Plane-Cap (PC) yield surface is assumed for the mortar, and shear strain energy criterion (Von-Mises) is applied for steel reinforcement. Dynamic Increase Factor (DIF) has been employed for the effect of strain rate (SR) on the mortar and steel reinforcement. The constitutive equation of PC model is employed on compression, while, orthotropic constitutive equation due to the damage effect is considered on tension. Shear cracking, bending cracking and compressive behavior of the beam were evaluated by using displacement-time histories as well as overall failure mode. The investigations enabled a better understanding of the behavior of beam elements under low velocity impact loads and it is confirmed that this numerical methods give good agreement with experimental results.
