An Edge-Based Smoothed Finite-Element Method for Vortex-Induced Vibration in Generalized Newtonian Fluids
(ASCE, 2022/11/01)Application of an edge-based smoothed finite-element method (ESFEM) to vortex-induced vibration (VIV) of a circular cylinder in generalized Newtonian fluids is presented. The incompressible Navier–Stokes equations incorporating ... -
Bayesian Optimal Sensor Placement for Damage Detection in Frequency-Domain Dynamics
(ASCE, 2022/12/01)Identification and monitoring of structural damage have a growing importance in the maintenance of aging structures. Specifically, an optimal sensor configuration capable of fully identifying structural damage is desired. ... -
Plastic-Damage Cap Model with Crack Closure Behavior for Concrete Modeling
(ASCE, 2022/11/01)A new isotropic plastic-damage cap model of concrete is proposed in this study to overcome the limitations (e.g., crack closure behavior) of the existing continuous surface cap (CSC) model in the hydrocode LS-DYNA. ... -
Efficient Multilayered Shell Model and Its Application in Large Reinforced Concrete Structures
(ASCE, 2022/12/01)When using the traditional multilayered shell element to perform material nonlinearity analysis of large structures, the computation time is often overwhelming because of the repeated updating and factorization of the ... -
Physics-Informed Neural Network Solution of Thermo–Hydro–Mechanical Processes in Porous Media
(ASCE, 2022/11/01)Physics-informed neural networks (PINNs) have received increased interest for forward, inverse, and surrogate modeling of problems described by partial differential equations (PDEs). However, their application to multiphysics ... -
Contact Stress and Rolling Loss Estimation via Thermomechanical Interaction Modeling of a Truck Tire on a Pavement Layer
(ASCE, 2022/12/01)Combined influence of temperature and mechanical deformations define the resulting contact stresses, heat flow, and rolling loss at the tire–pavement contact. In this study, the thermomechanical coupling of a hyperviscoelastic ... -
Nonlinear Elastoplastic Analysis of Plates Coupled with Mechanical Element–Based Isolation System
(ASCE, 2022/12/01)In general, the response of a system coupled with a vibration absorber is obtained by incorporating only elastic analysis under different loading conditions. However, the elastoplastic analysis is carried out for blast-resistant ... -
Soft Missing Rib Structures with Controllable Negative Poisson’s Ratios over Large Strains via Isogeometric Design Optimization
(ASCE, 2022/11/01)Soft network materials with biomimetic mechanical properties such as a negative Poisson’s ratio have important applications in tissue engineering, biomedical devices, and soft robotics. Several finite-element (FE)-based ... -
Buckling Behavior of Corroded Four-Sided Simply Supported Plates with Longitudinal Stress Gradients
(ASCE, 2022/10/01)This paper mainly investigated the buckling behavior of corroded four-sided simply supported plates with longitudinal stress gradients. The effect of corrosion surface topography on the buckling behavior of the four-sided ... -
A Hierarchical Bayesian Similarity Measure for Geotechnical Site Retrieval
(ASCE, 2022/10/01)Geotechnical site retrieval refers to the quantitative identification and extraction of sites similar to a given target site from predocumented generic sites in a database. This is known as the “site recognition challenge.” ... -
Semianalytical Solution of Consolidation of Composite Ground with Floating Impervious Column in Unsaturated Soil
(ASCE, 2022/10/01)A novel semi-analytical solution is proposed to analyze the consolidation behavior of composite ground with a floating impervious column in unsaturated soil based on the equal-strain hypothesis. The basic governing equations ... -
Structures That Can Be Made with Carbon Nanotube Fibers but Not with Other Materials
(ASCE, 2022/12/01)As already indicated by Galileo, the laws of rescaling for load-bearing structures do not follow the simple geometric proportion because the structural weight increases more than the structural capacity and can equally ... -
Exact Winkler Solution for Laterally Loaded Piles in Inhomogeneous Soil
(ASCE, 2022/11/01)A novel exact analytical solution is derived for the equation y(4)+xny=0 in the region x≥0, which is important for the analysis of piles in soil with stiffness varying with depth. To date, exact solutions for long piles ... -
