RISStudy on the Self-Sustaining Inlet Boundary Conditions for Numerical Simulation on Local Scour
Publisher: ASCE
Abstract: In previous numerical simulations of local scour, the steady flow is normally adopted as the inlet boundary condition, and the approach flow is always assumed as a homogeneous isotropic turbulence. In the present study, ...
Damage-Plastic Constitutive Model of Thin-Walled Circular Steel Tubes for Space Structures
Publisher: ASCE
Abstract: In this paper, we establish a coupled damage-plastic constitutive model in the scheme of small deformation assumption, based on a continuum damage mechanics model proposed by Lemaitre, for the thin-walled circular steel ...
Joint Planning of a Distribution System and a Charging Network for Electric Vehicles
Publisher: ASCE
Abstract: The spatial-temporal distribution of electric vehicle (EV) charging loads can be improved by implementing optimized charging scheduling, and by the joint planning of a distribution network (DN) and a charging network of ...
Numerical Simulation on Mass Transport in a Microchannel Bioreactor for Co-culture Applications
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microchannel bioreactors have applications for manipulating and investigating the fluid microenvironment on cell growth and functions in either single culture or co-culture. This study considers ...
Numerical Simulation of Mass Transport in a Microchannel Bioreactor With Cell Micropatterning
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Micropatterning of two different cell types based on surface modification allows spatial control over two distinct cell subpopulations. This study considers a micropatterned coculture system, which ...
Microfracture Characterization of Cement Paste at Early Age by Indentation Test
Publisher: American Society of Civil Engineers
Abstract: Fracture properties of cement paste at an early age are difficult to determine using conventional methods because of its low strength. By using an indentation technique, this paper reported a fracture test method for ...
Simulated Crack and Slip Plane Propagation in Soil Slopes with Embedded Discontinuities Using XFEM
Publisher: American Society of Civil Engineers
Abstract: To simulate the onset and growth of strong discontinuities (cracks or slip planes) and the failure mechanism in soil slopes with reasonable accuracy, a program was developed based on the existing extended finite-element ...
Classification of Soft-Story Buildings Using Deep Learning with Density Features Extracted from 3D Point Clouds
Publisher: ASCE
Abstract: Soft-story buildings are seismically vulnerable during earthquakes. The identification of such buildings is vital in seismic risk mitigation to assess the seismic resilience of a given urban region. Several studies have ...
Stability Analysis of Geosynthetic-Reinforced Slopes Considering Multiple Potential Failure Mechanisms Based on the Upper Bound Theorem
Publisher: ASCE
Abstract: The upper bound theorem (UBT) is widely used in the stability analysis of geosynthetic-reinforced slopes (GRSs). However, the existing research seldom considers multiple potential failure mechanisms when using the UBT to ...
XFEM Simulation of Soil Crack Evolution Process Considering the Stress Concentration and Redistribution at the Crack Tip
Publisher: ASCE
Abstract: Cracks are one of the major characteristics of soil structure failure. Successfully performed numerical simulation of the soil crack evolution process is conducive to the prediction of potential dangers. In recent years, ...
