Numerical simulation modeling of high velocity impact applied to reinforced concrete panel

In this tutorial Numerical simulation modeling of high velocity impact applied to reinforced concrete panel has been investigated. It is well known that concrete is much stronger in terms of compression than in tension. Because of its high com-pressive strength, and to enhance its tensile strength, tensile reinforcements are added to concrete elements subjected to tensile loading.A concrete material is subjected to static and dynamic loads. The static loads are permanent, whereas the dynamic loads vary over time. Among the dynamic loads, impact loads, which have catastrophic con-sequences on the structures, are included. An analysis of the impact behavior of reinforced concrete (RC) structures has been of significant interest in recent decades.In the present paper, the impact behavior of a reinforced concrete panel penetrated by a rigid steel ogive-nosed pro-jectile is numerically studied. The concrete material is modeled using the Johnson–Holmquist damage model (JH-2).You can see a figure of the assembled parts at below

Several constitutive models have been used for a description of the dynamic behavior of brittle materials under impact loads. In this paper, the Johnson Holmquist damage model (JH-2) is used to analyze the impact behavior of a reinforced concrete panel penetrated by a steel ogive nosed projectile. JH-2 is the second version of the Johnson–Holmquist (JH-1) ceramic model, which is able to simulate the impact behavior of brittle materials, such as the dilatation, pressure-strength dependence, and strain-rate effects resulting from damage

Concrete is modeled as three dimensional part ,beam as wire and bullet as rigid part.Dynamic explicit procedure is appropriate for this type of analysis.General contact by considering nodal erosion as input file has applied .Fix and symmetric boundary is assigned to the concrete part and intitial velocity is assigned to the bullet. The fine mesh is necessity at contact zone between two parts. After the simulation the damage parameter and stress….are be achievable.You can see some figures of this simulation at belwo
