Simulation rigid ball impact on the steel pipe with and without the CFRP reinforcement layers in Abaqus

In this tutorial, the Simulation rigid ball impact on the steel pipe with and without the CFRP reinfocement layers in Abaqus  has been investigated. The steel pipe is modeled as a three-dimensional shell part. The CFRP pipe is modeled as three-dimensional shell part and conventional shell section with eight layers is considered for it. You can see a figure of the assembled parts below

In the first analysis, the rigid ball impact to the steel pipe without CFRP reinforcement is done. The elastic-plastic material model with ductile damage criterion is considered to predict the damage during the impact. The dynamic explicit step with surface to surface contact is selected. The fixed boundary condition is assigned to two ends of the steel pipe and initial velocity is assigned to the rigid ball. After the first analysis, the plastic strain, damage, and displacement are available. In the second simulation, the CFRP is added to the middle of the steel part. The elastic material as lamina formulation and Hashin’s damage criterion is used to model proper behavior of the CFRP pipe.The conventional shell section with eight different layers is considered for the composite part. The surface to surface contact with contact property is selected between composite and rigid ball. The ideal contact between CFRP pipe and steel pipe is assigned. After the simulation all results are obtainable. The CFRP layers has a good effect on the reduction of plastic strain, displacement of the steel pipe and also its reduces the steel pipe damage. You can see some figures for the two simulations below
