Experimental Data on In-Plane Fiber-Waviness Defects in Composite Materials

This dataset contains experimental data from a study on manufacturing and characterizing in-plane fiber-waviness defects in composite coupons. The data supports the development and validation of computational models for composite structures. It includes measurements from ultrasound, digital image correlation, and a novel residual strain inspection technique.

Use Cases

• Validate computational models of composite failure using residual strain field measurements.
• Compare the effectiveness of ultrasound damage metrics versus residual strain-based damage metrics for predicting ultimate strength.
• Analyze the correlation between in-plane fiber-waviness defects and failure loads from specimens loaded to failure.

Strengths

• Data is derived from a large batch of manufactured composite specimens with controlled defects.
• Includes measurements from multiple non-destructive evaluation techniques: ultrasound, digital image correlation, and residual strain fields.
• Results demonstrate a specific finding that residual strain measurements are more effective than ultrasound for characterizing ultimate strength.

Limitations

• The exact number of specimens (rows) and measured variables (columns) is not specified in the provided input.
• Data is from a single experimental study, which may limit generalizability to other composite materials or defect types.
• The dataset's last update was in June 2020, potentially making it temporally stale for rapidly advancing fields.

Collection Method

Data was generated from an experimental study involving manufacturing composite coupons with localized in-plane fiber-waviness, followed by assessment using ultrasound, digital image correlation, and a novel residual strain inspection technique, and finally loading specimens to failure.
