A novel, meshless numerical method, called general particle dynamics (GPD), is proposed to simulate the initiation, propagation, and coalescence of three-dimensional (3D), pre-existing penetrating embedded flaws as well size effects large deformations rock materials. On basis nonlinear unified strength criterion, an elastic–brittle–plastic damage model was developed reflect growth, 3D macrofailure rocklike materials by tracing propagation cracks. Then, growth paths cracks were captured...
The relaxation strength of pore surfaces (ρ2) plays a pivotal role in transforming the nuclear magnetic resonance (NMR) T2 spectrum into size distribution, rendering it an indispensable parameter for characterizing microstructure via NMR techniques. In this study, spontaneous imbibition (SI) experiments, real-time measurements, and mercury intrusion porosimetry (MIP) tests were conducted on three sandstones with different porositirs. We propose novel approach calculating ρ2 using capillary...
Inclined piles are increasingly adopted in the foundation design of large-scale transmission line towers. Nine inclined pile tests were conducted red clay soil to investigate load-bearing and deformation behavior load transfer mechanism under vertical loading. The effects inclination length-to-diameter ratio on axial force, bending moment, shear lateral friction force analyzed. test results indicate that: (1) As angle increases, settlement increases (2) is smaller compared that corresponding...
Abstract Benefiting from the high theoretical energy density, low cost, and environmental protection, lithium‐sulfur (Li‐S) battery is one of most competitive candidates for next generation high‐energy‐density batteries. However, rate low‐temperature performances are poor due to terrible dynamics S cathode. Herein, a four‐electrode Li‐S cell integrated with an electrothermal interlayer designed realize internal heating. An composed Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 (LATP) carbon nanotube (CNT)...
A new numerical method, which is called the General Particle Dynamics (GPD) proposed to investigate zonal disintegration mechanism of isotropic rock masses around a deep circular tunnel subjected dynamic unloading as well stress distributions. constitutive model based on GPD method developed simulate phenomenon in masses. The number and size fractured nonfractured zones are determined using nonlinear unified strength criterion. It shown from results that loads high situ two dominant factors...
This paper studies the bearing mechanism of geosynthetic-encased stone column composite ground, using large-scale model tests and discussing effects geosynthetic encasements different lengths moduli on mechanism. Based tests, stress concentration ratio column, capacity deformation, axial radial stresses columns, failure modes ground improved by columns were analysed. The results show that fully-encased has a higher capacity, have ratio, smaller more uniform transfer over half load acting top...
Abstract To investigate the process of stick‐slip shear failure, small‐scale poly methyl methacrylate samples with friction faults and a high‐speed recording experiment system are used. The evolution stress slip displacement clearly shows both propagation failures local slip‐weakening behavior fault. distribution ratio τ yx / σ y along fault is great significance to determining nucleation location. interrelations among stresses, displacements, velocities, accelerations show details...
Abstract The principal objective of this work is to understand the effects brittleness on crack behaviors in rock, rock-like materials, and underlying fracturing mechanisms. Brittleness, as one critical parameters significantly affects mechanical properties behaviors. A better understanding can lead a more satisfactory characterization assessment overall performances rock mass. In study, experiments materials with two parallel preexisting flaws are conducted study brittleness, well...
In this paper, a novel meshless numerical method known as general particle dynamics (GPD) is developed to reveal the mechanism of rock fragmentation using tunnel-boring machine (TBM) cutters. Rock by one cutter and two cutters investigated GPD. The results obtained from GPD well agree with previous experimental results. Moreover, effects arrays flaws on are also studied stress fields efficiency. It found that significantly influence drivage efficiency depth chipping coalescence modes flaws.
