Atomistic Simulation of Short Crack Growth in Correlation with Fatigue Indicator Parameter
Publisher: ASCE
Abstract: Under time-varying extreme dynamic environmental conditions, fatigue damage could gradually accumulate with increased stress cycles at critical details of steel or other metallic structures. As a promising tool, a fatigue ...
Experimental Investigation of Self-Centering Beams for Moment-Resisting Frames
Publisher: ASCE
Abstract: Previously proposed self-centering moment-resisting frames relied on gap opening and closing in the beam–column interface to achieve recentering capability and energy dissipation capacity. The gap-opening mechanism in the ...
Preliminary Experimental Investigation of Loading Sequence Effects on Low-Cycle Bending Fatigue
Publisher: ASCE
Abstract: Bending fatigue, as one of the impact factors to reduce a metal’s service life, could play a critical role in fatigue life estimation of aerospace components and civil infrastructures, such as in machine gears, splined ...
Dislocation Density Evolution in Low-Cycle Fatigue of Steels Using Dislocation-Based Crystal Plasticity
Publisher: ASCE
Abstract: Dislocation accumulation caused by a crystallographic slip or plastic flow is one of the most critical factors for the growth of fatigue cracks. The dislocation density-based crystal plasticity method accounting for mobile ...
Three-Dimensional Equivalent Parameterized Beam Element for Nail Connections in Wood Residential Buildings
Publisher: ASCE
Abstract: Nail connections, serving as critical nodes in the loading path of wood residential buildings, could play a crucial role in structural analysis and damage prediction when the structures are subjected to winds and floodings ...
A Multiscale Crack Iteration and Remeshing Model for Low-Cycle Crack Propagation Evaluation
Publisher: ASCE
Abstract: A multiscale crack iteration and remeshing model was proposed and implemented to predict the low-cycle crack propagation behavior for steel. Crack propagation behavior was quantified by fatigue indicator parameters (FIPs) ...
3D Grain-Based Mesoscale Modeling of Short Fatigue Crack Growth for Bridge Weldments Considering Crack-Front Evolution
Publisher: ASCE
Abstract: To evaluate short crack growth and fatigue damage accumulation in steel structures, efforts have been made based on a two-dimensional (2D) grain-based model for fatigue life assessment under variable amplitude loads. ...
