Prosthetic Socket Liner Strain Data from DIC and FEA Comparison

Strain data from a study comparing Digital Image Correlation (DIC) measurements with Finite Element Analysis (FEA) predictions for a prosthetic socket liner. The dataset includes FEA and DIC strain data and an FEA model input file, created by Mohammadreza Freidouny and shared under a CC0 license. It was last updated on 2026-05-22.

Use Cases

• Validate Finite Element Analysis (FEA) models of prosthetic sockets based on experimental strain data.
• Compare optical strain measurement techniques (DIC) with computational predictions based on the provided datasets.
• Investigate liner strain patterns during specific loading tasks (vertical and half-step loading) mentioned in the study.

Strengths

• Includes both experimental (DIC) and computational (FEA) data for direct comparison.
• Provides the FEA model input file (INP format) for reproducibility.
• Released under a permissive CC0 1.0 public domain license.

Limitations

• Dataset scale is small (7.1 MB), and row count is unknown, limiting statistical power.
• Based on a single participant (unilateral transtibial prosthesis user), which limits generalizability.
• Column-level documentation is absent; field semantics must be inferred after download.
