摘要：
In order to study high-speed deformation of materials, a high-speed digital video camera has been developed by using a new MOS-type solid-state image sensor. The frame speed is controlled by a personal computer, and the maximum frame speed is 300 000 frames/s. The digital image taken by the high-speed video camera is analyzed by an image-processing system using a personal computer. In order to analyze the strain rate distribution, a new grid method using Fourier transform is developed. Through the use of this method, displacement, strain, velocity and strain rate distributions in a rubber tube in which an unloading wave is propagated are analyzed.
