【Abstract】 This paper describes the techique of using the combination of geometric moire method with high speed camerawork to measure the instantaneous deformation of a rectangular plate model with hole under impact loading due to a falling weight. Discussion to seperate interior stresses in the model by dynamic photoelastic method combined with this techique is also given.更多还原
