Quantifying The Evolution of Rock Stiffness During Pre-peak Cyclic Loading: Influence of Porosity and Lithology

Key Points

• Stiffness of rocks increases during pre-peak cyclic loading, showing the dynamic behavior of geological materials.
• A 40% increase in stiffness is related to changes in porosity and lithology, demonstrating their significance.
• Observational analysis of different rock types under cyclic loading highlights variances in stiffness responses.
• Results may support better predictions of rock behavior in engineering, enhancing safety and design strategies.
