Using the Vic-3D optical system and spayed speckle patterns, a localized plastic flow on the surface of porous plates of 0.85 mm and 2.7 mm thick loaded up to fracture in a quasi-static mode was traced and characterized. As seen, a 0.85 mm thick specimen indicated two strain-hardening distinctive parts in the stress-strain curve. Moreover, regions of localized strain are found that be wider than that of a 2.7 mm thick sample. It can be argued that by combining speckle patterns and quasi-static tension, one can effectively explore and predict the deformation behavior of a designing bone substitute made of porous SHS-TiNi.}, language = {en} }
