Study on contact problems in engineering structures

The basic idea, the main properties and the state-of-the-art for the research of theoretical and numerical analysis on contact problems in China and abroad are summarized. The optimum computational modeling of contact problems in sheet-space structures is introduced. For the sake of simplicity in computation, quadratic programming is adopted. It is shown that the modeling proposed can accurately explain the actual conditions of the interaction between the sheet and the skeleton in the sheet-space structure and will be a powerful computational basis for theoretical research and engineering design of engineering structures.
