Dear Majid Mohammadhosseinzadeh

When modeling a carbon fiber tube in ABAQUS, you can use the "Shell" section type to define the cross-sectional geometry and material properties of the tube. In the property module, you can create a new section and select "Shell" as the section type. Then, you can input the relevant dimensions (e.g., wall thickness, radius, etc.) and material properties (e.g., Young's modulus, Poisson's ratio, density, etc.) for the carbon fiber material.

Regarding the meshing, the appropriate mesh type for your carbon fiber tube depends on the complexity of the tube geometry and the simulation requirements. If the tube has a simple cylindrical shape, you can use a structured mesh such as a shell element mesh or a solid element mesh. Shell element meshes are commonly used for thin-walled structures like tubes and offer good accuracy and efficiency. Solid element meshes may be more appropriate for tubes with complex geometries or thicker walls.

In either case, it is important to generate a high-quality mesh that captures the features of the carbon fiber tube accurately. The mesh should have sufficient resolution in areas of high stress and deformation and should be refined near the tube ends and areas of localized deformation.

Additionally, when modeling a carbon fiber tube, it is important to consider the anisotropic nature of the material. Carbon fiber composites have different material properties in different directions, and this anisotropy should be accounted for in the material definition and mesh generation.

I hope this helps you with your tube hydroforming simulation with a carbon fiber tube in ABAQUS
