Digital Image Correlation of evolving restraining bend experiments in wet kaolin

Abstract

We document the evolution of two 15° strike-slip restraining bends within wet kaolin. Computer-controlled stepper motors displace one half of the split-box apparatus at a constant rate of 0.5 mm/min to induce dextral faulting in a 2.5 cm thick layer of wet kaolin. The basal plate discontinuity has a 15° bend with a 2 cm stepover distance. Prior to any loading we cut a vertical fault surface that follows the basal plate discontinuity into the wet kaolin with an electrified probe and wooden template.
