摘要：

Time-division digital speckle pattern interferometry to observe temporal variation of in-plane deformation fields of a whole process of plastic deformation until fracture was proposed. Experiment of tensile test of an aluminum-plate exhibited dynamic movements of successive fringe patterns which were very complicated. They suggest that plastic deformation propagates nonlinearly in the specimen by repetition of energy relaxation processes and concentration processes.
