A Mathematician, Scientist and Engineer, Dr. Shi Genhua newly proposed a “Contact Theory” published on Science China Technological Sciences (2015, 58(9): 1450-1496). The new theory is engineering-oriented, with solid mathematical proof and programmable. It provides the possibility to simulate the whole disastrous process: from continuous to fracture to blocky and to collapse in a unified manner. It can be used to solve the contact or impact problem among solids in rock engineering, mechanics engineering and robot engineering etc.
