Development of Rock Embedded Drilled Shaft Resistance Factors in Korea based on Field Tests
Applied Sciences, 2019 Load and resistance factor design (LRFD) is a limit state design method that has been applied worldwide. Because the data for determining LRFD factors in Korea has been insufficient, the resistance factors suggested by American Association of State ...

Structure‐Guided Dynamical Mechanics in Bioinspired Double Twisted Laminated Thin Films
Advanced Functional Materials, EarlyView.This work explores a dynamic mechanistic study of crack propagation and puncture testing via real‐time monitoring of crack initiation, propagation, and termination through nature‐inspired single and double twisted architectures fabricated from cellulose nanocrystals.

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

The Detection of Shaft Misalignments using Motor Current Signals from a Sensorless Variable Speed Drive [PDF]
, 2015 Shaft misalignments are common problems in rotating machines which cause additional dynamic and static loads, and vibrations in the system, leading to early damages and energy loss.

Performance of Screw Piles Under Axial Loading
GeotechnicsPiles with continuous helix (referred to herein as “screw pile”) is a new configuration of helical piles. It features a continuous helix spiraling several pitches around a smooth shaft forming a “threaded shaft”.

Shaft resistance of bored piles in sand
Acta GeotechnicaAbstract This work proposes an analytical method for the evaluation of the shaft load–settlement behaviour for bored piles in sandy soils. Key assumption is that the pile shaft response can be described through a simple law employing the initial (elastic) stiffness and the ultimate resistance.

Development of a Database for Drilled Shaft Foundation Testing (DSHAFT), June 2012 [PDF]
, 2012 Drilled shafts have been used in the US for more than 100 years in bridges and buildings as a deep foundation alternative. For many of these applications, the drilled shafts were designed using the Working Stress Design (WSD) approach.

Advanced Functional Materials, EarlyView.Al3+/Ta5+ co‐doping refines the primary particles of LiNiO2, reduces Li/Ni antisite disorder, and expands the c‐axis lattice parameter, thereby enabling faster and more homogeneous Li+ transport. Such rapid and homogeneous Li+ transport suppresses high‐voltage phase transitions and microcrack formation, ultimately improving the rate capability and long‐
