A method utilizing smart materials and structures for real-time load identification and structural response is useful in preventing structures from sudden and catastrophic failures without warning. Firstly the applications of loads identification technology in aeronautical and other areas are introduced. Then a system model about loads identification is established and a survey of strain sensing technologies in smart materials and structures, and mathematical methods to loads identification is presented. Finally, the research aspects and the key issues of loads identification are pointed out for further investigations..
