Abaqus Plug-in for 3D Unidirectional Composite RVE Generation
The Abaqus UD3D Plug-in is designed to automatically create a three-dimensional Unidirectional (3D) representative volume element (RVE) containing cylindrical inclusions within a cubic matrix.
This tool is ideal for microscale modeling of unidirectional composite materials, supporting both high and low fiber volume fractions.
Key Features of the 3D Unidirectional Composite RVE Abaqus Plug-in
Advanced Fiber Placement Algorithms
The plug-in combines three efficient fiber placement methods—Random Sequential Absorption (RSA), Random Around Particle (RAP), and Molecular Dynamics (MD)—to achieve high fiber volume fractions (up to 80%) in just a few seconds.
Variable Fiber Diameters
Users can define a range of fiber diameters, allowing for more realistic microstructure generation.
Automatic Intersection Detection
The code checks for fiber intersections using a user-defined tolerance, simplifying meshing by maintaining an adjustable minimum distance between fibers.
Boundary Periodicity Handling
If a fiber intersects the model boundary, the plug-in automatically creates the corresponding fiber on the opposite side to maintain geometric continuity.
Material Assignment and Orientation Control
Each fiber can be assigned individual material properties and orientations. Users can easily modify materials and choose whether or not to apply material orientation to the fibers.
Multiple Modeling Approaches for Meshing Flexibility
To minimize meshing issues in complex RVEs, the plug-in offers three modeling techniques:
Merge method
Embedded element technique
Voxel-based modeling
Compatibility with Periodic Boundary Conditions (PBC)
The plug-in supports periodic boundary conditions using the EngSoft_PBC3D Plug-in, applicable to all three modeling approaches mentioned above.
Full Compatibility with Abaqus Versions
EngSoft_UD3D is compatible with all versions of Abaqus software, ensuring that you can apply UD3D in Abaqus without worrying about version differences. This makes it easy to integrate into any existing workflow or upgrade your Abaqus version in the future.
