RISParticle-Based Numerical Manifold Method to Model Dynamic Fracture Process in Rock Blasting
Publisher: American Society of Civil Engineers
Abstract: A particle-based numerical manifold method (PNMM) is developed to investigate rock fracturing behavior under dynamic loading. The basic idea of PNMM is to represent the microstructure of rock with a group of particles and ...
Computational Methods for the Design and Prediction of Performance of Tidal Turbines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A design method based on a lifting line model is developed to determine the optimum radial circulation distribution on a turbine blade, which will produce the maximum output power for a given ...
A Thermodynamically Consistent 3D Breakage Model Considering Intermediate Principal Stress for Granular Crushing Problems
Publisher: ASCE
Abstract: A thermodynamically consistent three-dimensional (3D) continuum breakage model was developed to study the effect of intermediate principal stress. Such an effect has been long overlooked in most existing constitutive models, ...
Learning Mappings from Iced Airfoils to Aerodynamic Coefficients Using a Deep Operator Network
Publisher: ASCE
Abstract: This study abstracted the prediction of the aerodynamic coefficients of an iced airfoil as a mapping from the iced airfoil space to the aerodynamic coefficient space. Thus, a deep network called Airfoils2AeroNet that can ...
Physical Model Tests and Discrete-Element Simulation of Pile and Soil Displacement Response Induced by DOT Shield Tunneling Based on Transparent Soil Technology
Publisher: ASCE
Abstract: With the advantages of saving underground space, small construction impact, and saving cost, the double-O-tube (DOT) shield tunneling construction technology has been used many times in the tunnel construction of particular ...
