Rock Mechanics is a branch of engineering that studies the behavior of rock materials under various conditions. It focuses on understanding how rocks respond to forces, such as stress and strain, which is essential for construction projects like tunnels, dams, and foundations. This field combines principles from geology, physics, and engineering to analyze rock stability and strength. By using techniques like laboratory testing and numerical modeling, engineers can predict how rocks will behave in different environments, ensuring safety and efficiency in projects involving geological formations and earth materials.
