Paper Abstract

In this research a transient fringe image detection method is applied to restore the transient 3D deformation profile of an armor material during the penetration of a projectile. This method is based on the projection type moire topography. The deformed projection grating lines are generated by means of a line shift caused by the transient deformation of target material during impact with a high velocity projectile. The deviation of projected grating lines from the straight lines are measured at every pixel location. The shift of fringe image pattern reveals the height of transient deformation in perpendicular direction to the target surface. The principle of a modified projection type grating method and some experimental results are presented in this paper. The technique can be utilized to investigate the transient deformation of any armor material during impact with a projectile.
