Simulation dynamic tensile test of a concrete piece in Abaqus

In this tutorial Simulation dynamic tensile test of a concrete piece in Abaqus has been studied. The concrete part is modeled as three dimensional part. Normally concrete damage plasticity is used to model compression and tensile damage on the concrete pieces, during static or dynamic analysis. In this tutorial dynamic loading with Johnson-Holmquist material model are used. This material model commonly uses to model high velocity impact or blast loading over the brittle material but here to observe the separation and failure has been used.You can see a figure of the geometry at below

Dynamic explicit step and pressure load  with smooth amplitude has been used. To have a better failure at the middle of the concrete piece it is necessity to use fine mesh at that zone.To use JH2 material model VUMAT subroutine or modify input file by calling embedded subroutine can be used. In this tutorial second way is considered. After the simulation the damage and separation are obvious . You can see some figures of this simulation at below
