Paper Abstract

This paper presents a method, which is based on the Digital-image Correlation Method, for measuring the surface dynamic displacement field of objects under dynamic loading. A high-speed camera is used to record the deformed digital images of the specimen surface under dynamic excitation. By extracting two images at random intervals and use a computer algorithm, the dynamic displacement field of the object surface can be acquired accurately; the precision is in the order of microns.
