In this tutorial the Simulation internal explosion of a pipe with steel supporters in Abaqus has been investigated. The steel pipe is modeled as three-dimensional solid part, it can also be shell part. The upper and bottom supports are modeled as three-dimensional solid part. You can see a figure of the assembled parts below
To model the true behavior of the steel material, ductile, shear, and Johnson-Cook damage are used.The Johnson-Cook plasticity model: is a particular type of Mises plasticity model with analytical forms of the hardening, is suitable for high-strain-rate deformation of many materials, including most metals, is typically used in adiabatic transient dynamic simulations, can be used in conjunction with the Johnson-Cook dynamic failure model in Abaqus/Explicit, can be used in conjunction with the tensile failure model to model tensile spall or a pressure cutoff in Abaqus/Explicit, can be used in conjunction with the progressive damage and failure models
The ductile criterion is a phenomenological model for predicting the onset of damage due to nucleation, growth, and coalescence of voids. The Johnson-Cook criterion (available only in Abaqus/Explicit) is a special case of the ductile criterion in which the equivalent plastic strain at the onset of damage. The shear criterion is a phenomenological model for predicting the onset of damage due to shear band localization
The dynamic explicit step is appropriate for this type of analysis. The perfect contact among the parts are considered. The CONWEP blast load procedure is selected to define the internal explosion in the pipe. The fix boundary condition are assigned to two bed pales, the mesh should be fine to get the proper results
After finishing the simulation, all results such as stress, strain, damage, failure, force,… are available. You can see some figures of the results below.
