Simulation steel pipe reinforcement with CFRP layouts in Abaqus under three points bending

In this tutorial Simulation steel pipe reinforcement with CFRP layouts in Abaqus under three points bending has been studied. Circular hollow section (CHS) are widely used in many applications but predominantly used as pipelines in the oil and gas industry. Natural resources like oil and gas constitute the major share of global fossil fuel which is the dominant source of energy of the world. The advancement of human civilization and scarcity of natural resources like oil, natural gases, and minerals lead to explore deeper into the earth’s crust and to expand the venture in remote locations; eventually increasing underground, high pressure ashore and subsea drilling activities. Metal pipelines are the most efficient and safest ways to transport these natural resources over long distances. At present, most of the pipeline systems consist predominantly of steel pipes due to their high strength, relative to the simplicity of joints and low cost

The steel pipe and CFRP pipe are modeled as three-dimensional shell parts. You can see a figure of the assembled parts at belowElastic plastic material for steel pipe and elastic behavior as engineering constant with Hashin’s damage criterion for CFRP are used. Because of the large deformation, dynamic explicit step with mass scale to hasten the simulation is used. Surface to surface contact between rigid bodies and steel pipe-composite with a general contact to consider the other interactions are used. The contact between steep pipe and CRFP pipe is considered as a perfect contact. The two rigid bodies as supporters are fixed in all direction and the upper rigid body has movement with smooth step amplitude to apply smooth load rate. The mesh quality has a good effect on the bending results

After the simulation the deformation and bending, stress, strain, damage….are achievable. You can see some figures for this simulation at below
