Shear Plane Analysis of Deployable Anchors and Insights from X-ray Microtomography
Shear Plane Analysis of Deployable Anchors and Insights from X-ray Microtomography
This paper investigates the behavior of deployable anchors using plane strain and X-ray microtomography (CT) experiments. A deployable structure is a system that changes size and shape under applied loads, presenting a novel approach to reduce transportation and life cycle costs of materials without sacrificing load-carrying capacity. Presented is the experimental methodology to determine the increase in the shear plane in sandy soil using deployable underground anchors. Ink tacking technique was employed to locate the shear plane. This study finds that the ink tracking technique captures the shear plane effects in sandy soil for deployable awns in ground anchors. Moreover, bar cross-section optimization represents origami behavior under in-plane and out of plane loading. In addition, the initial results of the deployable geosystem - soil interaction from CT are presented. Experimental testing involves subjecting a scale model deployable system to displacement-controlled loading in sand. Utilizing CT scanning with 35 m voxels, images are captured to track the bending of the anchor's awns (compliant appendages).
