Hydrodynamic ram from Zr55Cu30Al10Ni5 fragmentation: experiments, SPH/ALE simulations, and pressure normalization

Key Points

• Hydrodynamic ram was observed during the fragmentation of Zr55Cu30Al10Ni5 alloy, indicating significant energy transfer.
• The highest pressure recorded reached 220 MPa in the tests, reflecting the impact of material properties on fragmentation effects.
• Observational analysis involved SPH and ALE simulations, demonstrating the utility of computational methods in predicting material behavior.
• Findings suggest potential applications in improving performance in fields reliant on high-energy impacts and material strength.
