In this tutorial Simulation low velocity impact on reinforced concrete beam in Abaqus-Damage investigation has been studied .Reinforced concrete (RC) structures have been widely used for centuries but the understanding of the impact behavior of these structures against impact loads is still limited. Several design codes based on an equivalent static approach provide general principles for the design of structures under impact loads.The impact force and displacement of RC beams can be predicted by using the common spring-mass models of either single degree of freedom (SDOF) or two DOF
The concrete beam is modeled as three dimensional part, the steel beams are modeled as wire part and the projectile is modeled as rigid body. You can see a figure of the assembled part at below
The steel material is modeled as a elastic plastic material with ductile damage property. The concrete material model is so important and Abaqus provide some material models in it’s library but they are not suitable to predict damage and failure. In this simulation Johnson Holmquist material model is used. Dynamic explicit procedure is appropriate for this type of analysis. The beams are used as embedded region in the concrete host. Surface to surface contact with penalty contact behavior is used to define contact. Initial velocity is assigned to projectile. The quality of mesh has a good effect on the result.
After the simulation damage,stress,strain and load diagram can be achievable. You can see some figures of this simulation at below
