Deformation Characteristics of the Tensile Specimens of Steel Sheet in Local and Global Area Using Videoextensometry

Original language description

It is generally known that high strength is always accompanied by low ductility for various structural materials [1]. With increasing yield stress and ultimate tensile strength plasticity characteristics, such as elongation, plastic strain ratio r and strain hardening exponent n decrease. The ratio of yield stress to ultimate tensile strength Re/Rm represents the ability to plastic deformation, called plastic reserve and for good formability it reaches a minimum value. The main goal of this study is thecomparison between deformation characteristics in the global and local area using a non-contact experimental technique, videoextensometry, for measuring strain during tensile loading at uniform deformation. Steel sheet with 3 mm thickness, made from deep-drawing steel, was used for the investigation on specimens oriented perpendicularly to the rolling direction. Despite similar true stress - true strain curves measured in local and global areas for individual materials, both values of p
