Abstract In order to systematically evaluate the damage degree in Jinping deep tunnels during excavation, an improved SPH algorithm with good Lagrangian characteristics is introduced. By modifying derivative of traditional kernel functions, brittle failure processes particles are realized. The ‘Fissure Searching Generating Method’ (FSGM) has also been used determine establishment joints and tunnel excavation parts. Based on engineering practices, numerical models set up, degrees under...
The simulation of crack propagation processes in rock engineering has been not only a research hot spot among scholars but also challenge. Based on this background, new numerical method named improved kernel smoothed particle hydrodynamics (IKSPH) put forward. By improving the function traditional (SPH) method, brittle fracture characteristics base particles are realized. domain searching (PDSM) forward to generate arbitrary complex fissure networks. Three examples analyzed validate...
The deep learning-based method demonstrates superior capability in high-temperature deterioration analysis of rock materials through scanning electron microscopy (SEM) characterization. However, the blurred boundaries between particles and pore structure presented SEM images always affect training efficiency. Hence, this study, metal intrusion technology backscattered (BSE) observations are applied to assist a model analyze exposed different levels high temperatures. >2000 micro for each...
Complex bedding properties and in situ stress conditions of shale formation lead to complex hydraulic fracturing morphologies. However, due the limitations traditional numerical methods, simulation still needs further development. Based on this, liquid–solid interaction modes SPH governing equations considering force have been introduced. The smoothing kernel function method is improved by introducing fracture mark ξ, which can realize rock processes. boundary applied mapping “stress...
Evaluation of slope stability under water level fluctuations is an important topic in the Three Gorges Reservoir (TGR) China. However, most previous studies regarded soil as isotropic material, or only considered influence anisotropy ratio (kr = kx/ky) but ignored direction (α). Meanwhile, pore pressure–stress coupling was rarely numerical simulations. In present study, SIGMA/W and SLOPE/W modules Geo-studio are utilized to carry out simulation Caipo drawdown reservoir level, (kr) well (α)...
This paper presents an electrochemical-thermal coupling model of 5Ah NCA-graphite pouch battery to analyze the heat generation mechanism. The simulation result indicates that total increases with current and polarization is dominant. negative electrode higher than positive electrode, electrochemical reaction ohmic are those electrode. Then four design parameters were selected, their effects on characteristics from different sources analyzed in detail. results indicate increase capacity...
In order to study the ductile deformation characteristics and failure process of plain concrete under uniaxial compression, this paper proposes a new constitutive model. The model was used fit analyze curve compressive various degradation forms compared with traditional models. Finally, quantitatively predict stress-strain in different periods set freeze-thaw measured data. results show that, model, is simple form has few parameters, numerical value parameter can reflect capacity concrete....
