The available research dataset consists of several files associated with the published study (DOI: 10.1016/j.conbuildmat.2025.140309). The following is a detailed description of each file:

Test Images and Videos.ZIPThis archive contains selected photos and videos recorded during the experimental tests. Additional related images are provided in the original publication.

Algorithm.PDFThis document details the algorithm presented in Section 4 (Computational Modeling) of the original publication. The algorithm was used to develop a Python script that generates prism (beam) samples with user-defined dimensions and randomly distributed short fibers. The user can specify the geometric characteristics of the fibers, the fiber volume fraction, the minimum distance between fibers and between fibers and the prism edges, and the fiber settlement percentage. Each step of the algorithm is explained in this document, along with the associated functions, mathematical formulations, and control checks implemented to prevent fiber intersections, ensure that fibers remain within the sample boundaries (while considering tolerance distances such as aggregate size in concrete), and account for fiber settlement during casting.

Script.PYCThis file is the compiled Python script based on the aforementioned algorithm. It is designed for immediate compatibility with Abaqus CAE, requiring no additional packages. The default parameters assigned within the script are as follows:

BEAM_WIDTH: 40.0 mm

BEAM_HEIGHT: 40.0 mm

BEAM_LENGTH: 160.0 mm

FIBER_DIAMETER: 0.5 mm

ENDING_LENGTH: 6.0 mm (length of each ending part)

MIDDLE_LENGTH: 23.0 mm (length of the middle part)

TOLERANCE_FIBER: 0.5 mm (minimum distance between fibers)

TOLERANCE_EDGE: 0.5 mm (minimum distance from fibers to beam edges)

SETTLEMENT_PERCENTAGE: 10%

VOLUME_FRACTION: 2%

Readme.PDFThis comprehensive document provides detailed, step-by-step instructions on how to use the script. It elaborates on all functions and capabilities of the code and provides guidance on how the script may be modified.

Simulation Images and Videos.ZIPThis archive contains images and videos captured during the simulation process. Additional simulation visualisations are available in the original publication.
