Analysis of hysteretic behavior of anchored reinforcing bars

, 1997
This paper presents the analysis of the hysteretic behavior of anchored reinforcing bars with a new finite element model. The Smile element is based on the interpolation of the steel stress distribution and thus, is flexibility-based. It is characterized

Voltage‐Driven Non‐Volatile Interconversion Between Giant Single‐Domain and Multidomain Magnetic States in a Multiferroic Heterostructure

Advanced Science, EarlyView.
Non‐volatile voltage control of magnetic configurations is achieved in a strain‐coupled multiferroic heterostructure. Voltage pulses reversibly interconvert giant single‐domain and multidomain magnetic states, which remain stable at zero applied voltage. ABSTRACT Voltage control of magnetic states in multiferroic heterostructures represents a promising

Modeling of Hysteretic Behavior of Beam-Column Connections Based on Self-Learning Simulation [PDF]

, 2007
Current AISC-LRFD code requires that the moment-rotation characteristics of connections be known. Moreover, it requires that these characteristics be incorporated in the analysis and member design under factored loads (AISC, 2001).

Sustained Self‐Powered Real‐Time Vibration Monitoring Through Integrated Nonlinear Harvesting and Energy‐Aware Wireless Sensing

Advanced Science, EarlyView.
A self‐powered vibration sensing platform integrates a quasi‐zero‐stiffness piezoelectric harvester, synchronized electric charge extraction, energy management, and wireless ADC acquisition. Ambient vibration is simultaneously harvested as energy and digitized as information, enabling sustained real‐time waveform monitoring without external power.

Hysteretic Behavior of the Lubricated Curved Surface Slider Under Variable Contact Pressure

Advances in Civil Engineering
Lubricated curved surface sliders (L-CSSs) with modified ultrahigh-molecular-weight polyethylene (M-UHMWPE) are highlighted in the prevention of bearing failure due to the high-temperature degradation of friction materials during high-speed operation ...

Suppressing Morphological and Energetic Disorder in Copper Antimony Sulfide‐based Hole‐Transporting Materials via Ligand–Precursor Engineering for Efficient and Stable Perovskite Solar Cells

Advanced Science, EarlyView.
Sulfur‐precursor and ligand engineering regulate the nucleation, morphology, and energetic disorder of CuSbS2 nanocrystals for dopant‐free inorganic hole‐transport layers in perovskite solar cells. Thiourea‐assisted synthesis combined with optimized OAm/OAc coordination suppresses excessive anisotropic growth, enabling mixed plate‐like/quasi‐spherical ...

Optically Tunable Threshold Switching and Thermally Activated Transport in Planar Ag/MAPbI3 Thin Single‐Crystal Devices

Advanced Science, EarlyView.
Planar Ag/MAPbI3 thin single‐crystal halide perovskite devices show ultralow dark current and optically tunable threshold switching. Illumination enhances the polarity‐dependent hysteresis and shifts the switching voltage, whereas temperature‐dependent measurements reveal thermally activated, contact‐limited transport, underscoring the central role of ...

Experimental and Analytical Study of a Segmented Buckling Restrained Brace

Buildings
Buckling-restrained braces (BRBs) are widely recognized as effective energy-dissipation components that enhance the seismic resilience of structures. This study introduces a segmented buckling-restrained brace (S-BRB), composed of a Q235 steel core plate,
