Multi-Scale Finite Element Modeling of 3D-Printed Scoliosis Orthoses

Giving access to multi-scale finite element modeling and experimental validation data for 3D-printed scoliosis orthoses, developed by Thomáy-Claire Hoelen and published in 2026. It encompasses microscale tensile and compression tests, mesoscale strain distributions from digital image correlation, and macroscale full-brace reaction force measurements.

Use Cases

• Validating finite element models using experimental reaction force measurements from full-brace tests
• Analyzing nonhomogeneous strain distributions in 3D-printed organic subunits via digital image correlation data
• Optimizing 3D-printed orthotic designs by redistributing material based on simulated stress regions and plastic deformation observations

Strengths

• Validated against experimental data with less than 2% deviation in macroscale reaction forces
• Includes mesoscale strain field validation with 82% histogram overlap
• Covers three distinct scales: micro (specimens), meso (subunits), and macro (full brace)

Limitations

• Highly specific to scoliosis orthoses and may not generalize to all 3D-printed lattice structures
• Small sample size focused on model validation rather than a large population study
