Simulation rigid impact on the ultra-high performance fiber reinforced concrete slab in Abaqus

In this tutorial, the Simulation rigid impact on the ultra-high performance fiber reinforced concrete slab in Abaqus has been investigated. UHP-FRC is a new class of concrete that has been developed to give a significantly higher material performance in comparison to its concrete counterparts. UHP-FRC exhibits superior mechanical characteristics, including a compressive strength of greater than 150 MPa, high elastic modulus, high elastic limit, a tensile strength in the range of 8–۱۵ MPa, strain hardening in tension, fracture energy of several orders of magnitudes of traditional concrete and high post-cracking capacity. The ultra-high compressive strength of UHP-FRC is achieved by using the optimum combination of very fine aggregates that ensure homogeneity and dense packing. The UHPFRC slab is modeled as a three-dimensional solid part. The bars are modeled as three-dimensional wire parts. The rigid projectile is modeled as a shell part. You can see a figure of the assembled parts below

The Concrete Damaged Plasticity is used to model the UHPFRC slab under the impact load. The CDP model can predict tension and compression damage during the impact. The data were extracted from the reference paper. The steel material with elastic-plastic behavior is selected for the bars. The dynamic explicit step is appropriate for this type of analysis. The general contact algorithm with contact property is implied to consider all contacts. The bars are embedded inside the concrete host. The fixed boundary condition is assigned to the corners of the slab and initial velocity is selected for the rigid body. The mesh should be fine at the contact zone to have a better performance

After the simulation, all results such as stress, strain, tensile and compression damage, displacement, and….are obtainable. You can see some figures for the results below
