Abstract
Time-division digital speckle pattern interferometry to observe tempor al variation of in-plane deformation fields of a whole process of plas tic deformation until fracture was proposed. Experiment of tensile tes t of an aluminum-plate exhibited dynamic movements of successive fring e patterns which were very complicated. They suggest that plastic defo rmation propagates nonlinearly in the specimen by repetition of energy relaxation processes and concentration processes.
