Dynamic Biomechanical Response of Head-Neck Systems on Sand and Artificial Turf Surfaces: A Hybrid Experimental and Computational Study
Description
This dataset includes experimental and numerical data used to evaluate head and neck injury metrics under different sand moisture conditions and artificial turf configurations. The biomechanical indices include Head Injury Criterion (HIC), Time of Interaction (TOI), and Neck Injury Criterion (Nij). The dataset includes four Excel files and one ReadMe document containing measurement definitions, formulas, and protocols.

Steps to reproduce
The dataset was generated through a hybrid experimental–computational workflow designed to evaluate head and neck injury metrics under different surface conditions (sand depths of 50 mm, 100 mm, 150 mm, and artificial turf). Experimental drop tests were performed using an aluminum headform instrumented with single-axis and tri-axial accelerometers. Each drop test was conducted from controlled heights (1.2–1.5 m) under two moisture conditions (0% dry and 5% wet). Raw acceleration signals were processed in MATLAB and SPSS to compute HIC, Time of Interaction, peak accelerations, and minimum acceleration values. For computational reproduction, LS-DYNA models were developed following the same boundary conditions and material properties used in the physical tests. Details of instrumentation, sampling rate, filtering, and computational parameters are included in the attached ReadMe file. To reproduce the results: 1. Select the dataset corresponding to surface type and depth. 2. Use the provided columns to compute HIC and TOI, or re-process raw values as needed. 3. Follow the procedures described in the ReadMe for re-running LS-DYNA simulations or reanalyzing the experimental data. All measurement definitions, formulas, and experimental protocols are included in the ReadMe.
