Volume Change Measurements Using 2D DIC System

The presented study focuses on measuring volume changes in elastomeric materials using digital image correlation (DIC), specifically the 2D DIC universal system and video-extensometer directly implemented to testing machine. Optical measurement methods were applied two-dimensional (2D) configurations during mechanical of dumbbell-shaped test specimens under uniaxial tension. measured data used determine dependencies bulk modulus Poisson's ratio strain. obtained by both correspond model behavior rubber-like materials. Compared video-extensometer, provides a tool for transverse longitudinal strain, wide range post-processing options, including change input parameters, settings, or calculation relations.
