Contact mechanics
Contact mechanics is the branch of mechanics that studies deformation of solid bodies pressed against each other, predicting contact area size, shape, pressure, and stresses.
Cylinder stress
Cylinder stress is the set of stresses in the wall of a pressurized cylindrical vessel: hoop, longitudinal, and radial. In thin walls, hoop stress is pr/t, exactly twice the longitudinal.
Maugis adhesion map
The Maugis adhesion map is a regime diagram for adhesive contact of elastic spheres, drawn by Johnson and Greenwood in 1997 to place the JKR and DMT models as limits.
Mechanical unfeelability cloak
A mechanical unfeelability cloak is a metamaterial coating that makes an embedded object elastically undetectable by touch, first demonstrated at the Karlsruhe Institute of Technology in 2014.
Mindlin contact theory
Mindlin contact theory, due to Raymond D. Mindlin in 1949, describes how two elastic bodies pressed together respond to a small tangential force: slip occurs at the contact edge while the inner core sticks.
Shell theory
Shell theory is the branch of structural mechanics describing the deformation, stress, vibration, and stability of thin curved solid bodies such as domes and pressure vessels.
