4D-Printed Honeycomb Metamaterial Compression and Cyclic Test Data

Experimental data for 4D-printed polylactic acid honeycomb metamaterials with positive, negative, and zero Poisson’s ratios. The dataset includes force–displacement responses under two crosshead velocities and results from six deformation–recovery cycles. It was authored by Sheng Huo and last updated on May 17, 2026.

Use Cases

• Analyze topology-dependent rate sensitivity based on force–displacement responses at 0.025 and 25 mm/s.
• Study anisotropic compression behavior based on data from two orthogonal loading directions.
• Evaluate cyclic energy absorption and mechanical retention based on results from six deformation–recovery cycles.
• Model thermally activated shape recovery based on shape recovery ratio data.

Strengths

• Data supports calculation of multiple key metrics: structural stiffness, plateau force, specific energy absorption, mechanical retention, and shape recovery ratio.
• Includes experimental results for three distinct Poisson's ratio configurations (positive, negative, zero).
• Covers both quasi-static (0.025 mm/s) and low-velocity (25 mm/s) compression testing.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
