【Abstract】 This work explores the traditional method of measuring stress field of deforming plate, and points out the shortage of the old method. And it gives a method based on Digital Image Analysis to measure the stress field of deforming plate. The principle of the method is given. It also gives the improvement of the new method. And finally it not only shows the future of the method, but points how to improve the method.更多还原
