Whitney Barnes, Joel New, James Pierce, John Walker, James Mainquist, Fred King, Jimmy Elliott, Scott Hammack, Rebekah DeckerThe video shows the stretch plate subjected to 20% cyclic linear stretch at 1 Hertz and temporal changes in intra-plate displacement field of strain computed by digital image correlation (DIC). The plate is patterned by aerosol spray black paint to create a stochastic speckling pattern of fine points for DIC analysis. The DIC computed strain is overlayed on the patterned stretch plate with a strain magnitude color scale of 0 - 0.26 m/m. The graph shows changes in average intra-plate strain through time.
