RISComparative Study of 2D and 3D Micromechanical Discrete Element Modeling of Indirect Tensile Tests for Asphalt Mixtures
Publisher: American Society of Civil Engineers
Abstract: Based on imaging and the discrete element method (DEM), this study mainly aims to compare the two-dimensional (2D) and three-dimensional (3D) micromechanical modeling of the indirect tensile (IDT) tests for asphalt mixtures. ...
Micromechanical Analysis of Asphalt-Mixture Shear Strength Using the Three-Dimensional Discrete Element Method
Publisher: American Society of Civil Engineers
Abstract: This study investigated the shear strength of asphalt mixtures and its influence factors by using a three-dimensional (3D) discrete-element method (DEM). The uniaxial penetration test, a shear strength test method for ...
Analysis of the Fracture Mechanism of Concrete Gravity Dams under Explosive Loading
Publisher: American Society of Civil Engineers
Abstract: AbstractAs a critical strategic target and a large hydraulic structure, the dynamic response
of concrete gravity dams under explosive loading has been extensively studied, yielding
mature research results. However, there ...
Tailorable Thermal Expansion of Lightweight and Robust Dual-Constituent Triangular Lattice Material
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Current studies on tailoring the coefficient of thermal expansion (CTE) of materials focused on either exploring the composition of the bulk material or the design of composites which strongly depend on a few negative CTE ...
Optimized Joint Flood Control and Peak-Shaving Operation for Multireservoir Systems Based on Critical Reservoir Identification
Publisher: American Society of Civil Engineers
Abstract: AbstractAs a typical high-dimensional, multiconstraint optimization problem, the joint flood
control operation of reservoir groups faces challenges such as the curse of dimensionality
and the coupling of multiple constraints. ...
