Abstract:

Structural damage evaluation has all the time attracted broad attention due to its close relation to practical applications. With reference to up-to-date overseas and home literature, the paper has concentrated on methods of optical fiber sensing, stress wave and mechanical impedance, which is based on smart materials and structures, on the basis of a concise review of conventional methods of structural damage evaluation. Applications of the methods in engineering have been presented, and some problems and further research work of the methods have been discussed.

Key words: smart materials and structures, damage evaluation, opt ical fiber sensing, stress wave, mechanical impedance
