Local Yield Stress and Plastic Events in 3D Model Glasses

Three glass samples were probed at 10x10x10 testing sites with variations in probing region size from 2.5 to 10 atomic distances. The data, associated with research from Johns Hopkins University, supports the investigation of local yield surface anisotropy and the prediction of plastic events under shear loading.

Use Cases

• Predicting the location of plastic events based on local yield stress measurements.
• Quantifying the anisotropy of local yield surfaces under varied loading directions and triaxiality.
• Optimizing the parameterization of local probing methods for computational glass models.
• Analyzing correlations between boundary loading conditions and triggered plastic regions.

Strengths

• Data is derived from three distinct computational glass samples, providing a basis for comparison.
• Probing was conducted at 10x10x10 sites per sample, suggesting a systematic spatial analysis.
• The study investigates multiple probing region sizes (2.5, 3.75, 5, 7.5, 10 atomic distances) and loading variations.

Limitations

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