Rock Mechanics Letters is a dedicated to the rapid communication of significant advances in rock mechanics and its applications. Serving researchers, engineers, and practitioners in geotechnical engineering, mining, civil engineering, engineering geology, and geosciences, the journal covers a wide range of topics including experimental and theoretical rock mechanics, computational methods, underground excavation, rock slope stability, and AI technology in rock masses. Specific topics also include but are not restricted to energy related rock mechanics, petroleum engineering, geothermal systems, and planetary science.
