Abstract This study establishes a method to measure the displacement and
strain of rubber with large and fast deformations using digital image correlation.
In order to elucidate the mechanism of growth of a crack and to investigate the
complex behavior of a crack tip, which is important for that purpose,
displacement and strain near the crack where large strains are locally generated
by stress concentration are measured. A displacement restraint rubber sheet of a
strip fixed at upper and lower ends with an initial crack is used as a test piece. A
constant rate displacement load is applied to it, its… More >
