Simulation outputs from a 3D finite element model analyzing fracture intensity increases due to interacting blast waves. The model incorporates the Johnson-Holmquist-2 constitutive model and a tensile failure model for brittle materials under high strain rates. Data includes results from four explosion models on two different rock types.
Use Cases
- Validate the combined Johnson-Holmquist-2 and tensile failure model's energy-conserving algorithm using the provided simulation outputs.
- Analyze self-organizing damage patterns and fracture-like structures from the simulation data to compare with experimental observations.
- Study the mesh dependence of fracture intensity results on 2D planes and 3D volumes across different mesh densities.
- Assess model predictive capability by examining fracture intensity outputs for a range of materials, explosive waves, and geometries.
Strengths
- Model incorporates material heterogeneity through variation of properties at the element level.
- Simulations cover four distinct explosion models on two different rock types.
- Model handles damage due to both compression and tension and relies on measurable material properties.
Limitations
- Dataset scope is limited to four specific explosion models, restricting generalizability.
- Sample size and specific row/column counts are unknown, limiting analytical scale assessment.
- Data represents numerical simulations, not direct physical measurements, introducing model-dependent assumptions.
