Macro–micro mechanical impacts of particle shape on the scale effect of rockfill materials

Key Points

• The scale effect is impacted by the shape of rockfill particles, altering both macro-mechanical and micro-mechanical behaviors.
• Initial findings indicate that specific particle geometries can lead to up to 30% variation in mechanical strength.
• Analysis includes a comparative review of various particle shapes and their performance under load conditions.
• Highlights the necessity to consider particle morphology for future engineering applications, improving material performance.
