【Abstract】 The traditional method of measuring the strain field of deformed sheet is discussed. The work explores the shortage of the old method. And it gives a method based on digital image analysis to measure the strain field of deformed sheet. 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 also points out where should be improved.更多还原
