The Abaqus RVE random rectangular fiber composite plug-in by EngSoft helps you easily generate 2D representative volume elements (RVE) with random rectangular fibers. It automates fiber placement, intersection checking, and RVE creation for accurate composite modeling in Abaqus.

The EngSoft_RandRec is a powerful Abaqus plug-in designed to generate two-dimensional (2D) representative volume elements (RVE) containing rectangular inclusions or short discontinuous fibers distributed randomly within a rectangular matrix.
This tool is ideal for mesoscale modeling of random fiber-reinforced composites, wood-polymer composites, and concrete materials with rectangular inclusions.

By using the Random Sequential Adsorption (RSA) algorithm, the plug-in precisely places rectangular fibers with user-defined dimensions, orientations, and intersection tolerances. It enables the creation of realistic microstructures that are easy to mesh and suitable for accurate finite element simulations.

 Key Features of Abaqus RVE random rectangular fiber composite plug-in

• Random RVE generation with rectangular inclusions: Creates realistic 2D microstructures of discontinuous fibers or rectangular particles.

• Advanced RSA algorithm: Ensures non-overlapping placement of inclusions with high volume fractions.

• Customizable fiber geometry and orientation: Define ranges for length, width, and angle for each inclusion.

• Intersection control: User-defined tolerance allows accurate overlap detection and smooth meshing.

• Boundary periodicity: Automatically replicates intersecting fibers on opposite sides to maintain periodic geometry.

• Independent material assignment: Each fiber can have unique material and orientation properties for flexible modeling.

• PBC compatibility: Fully compatible with EngSoft_PBC2D for applying periodic boundary conditions (PBC) after RVE generation.

 Applications

• Modeling of short random fiber composites

• Simulation of wood-polymer composite microstructures

• Analysis of concrete or cementitious materials with rectangular inclusions

• Finite element studies of discontinuous or irregular fiber-reinforced materials

 Compatibility and Integration

After generating the RVE, users can directly apply periodic boundary conditions using the EngSoft_PBC2D plug-in. This ensures accurate periodic response under mechanical loading and improves convergence in Abaqus Standard analyses.
