Contact mechanics is the study of how solid surfaces interact when they come into contact. It examines the forces, deformations, and stresses that occur at the interface of two bodies. This field is essential in understanding wear, friction, and the overall performance of materials in various applications, such as engineering, tribology, and material science. The principles of contact mechanics are applied in numerous industries, including automotive, aerospace, and manufacturing. By analyzing how surfaces behave under load, engineers can design better components, improve durability, and enhance the efficiency of machines. This knowledge is crucial for optimizing performance and preventing failure in mechanical systems.
