A novel approach to characterize the direct shear pullout behavior of single hooked steel fibers
, 2021 Fibers crossing sliding crack planes have a positive influence on capacity because they can transfer shear load as dowels. Such behavior was evidenced by several researches that investigated the direct shear performance of Fiber-Reinforced Concrete ...

Scale Effect in Anchor Pullout Test by Centrifugal Technique
Soils and Foundations, 1988 ABSTRACT Centrifugal technique can be applied to the model tests of bearing capacity, earth pressure, anchor pullout, etc. in sand. In this method, the soil mechanics law of similarity is satisfied by performing the model tests in the centrifugal field.

Push the Limits: Human‐Like Multimodal Extreme Embodied Intelligence for Autonomous Racing
Advanced Robotics Research, EarlyView.Autonomous racing tests embodied intelligence under extreme control limits of speed, actuation, and decision‐making. Inspired by human multimodality, we present Apex, an embodied agent deployed on a super‐formula racing car at Yas Marina. Integrating physics‐informed perception, multimodal learning, and tasking, Apex cuts lap times by 15% and achieves ...

Stochastic Entanglement of Deterministic Origami Tentacles For Robust Robotic Grasping
Advanced Science, EarlyView.This study introduces an origami tentacle gripper to robustly grasp objects‐in air, underwater, and even in orbital space‐by exploiting a synergy between local, deterministic deformation programming and global, stochastic entanglements. A single origami tentacle can be designed to coil with a simple tendon pull.

The Evaluation of Pullout Tests of An Expandable Newly Designed Screw
Kafkas Universitesi Veteriner Fakultesi Dergisi, 2013 Biomechanical evaluation of pullout forces of newly designed cortical screws with openable tips was done in the tibia bone of the young bulls. Newly designed expandable titanium 14 cortical screws with openable tips were inserted in fresh tibia bone. Of these screws, 7 were used as controls.
