TRENDS OF DEVELOPMENT IN MECHANICS IN THE EARLY 21ST CENTURY

The history of mechanics is reviewed in the light of the position and functions of mechanies in the development of science and technology:the understanding of natural lows and solution of engineering problems,Some major research topics are discussed in solid mechanics,fluid mechanies,general mecha-nics and in the area of mechnies-related cross-disiplines. Trends of mecha-nics development in the 21st century(especially in its carly period) is also given
