DEM study of the alteration of the stress state in granular media around a bio-inspired probe

Yuyan Chen et al.

Summary: This study investigates a probe that utilizes a self-contained anchor to advance its tip into soil, inspired by penetration strategies of marine and earthworms, razor clams, and plants. The study finds that the expansion of the anchor induces stress relaxation around the probe's tip and stress increase around the anchor, facilitating penetration. Longer anchor and shorter anchor-to-tip distance are found to be more effective in promoting tip advancement by inducing greater stress relaxation ahead of the tip.

Directionally dependent strength and dilatancy behavior of soil-structure interfaces

Hans Henning Stutz et al.

Summary: The experimental study found that the shear behavior of soil-structure interfaces varies depending on the direction of relative displacement and the geometry of asperities. The ratio of asperity length to height is shown to capture the effect of asperity geometry on interface shear response. The results suggest that implementing snake skin-inspired profiles on geotechnical structures may enhance performance and efficiency.
