Abstract Microbially induced calcium carbonate precipitation (MICP) has attracted much attention as a promising green technique for soil improvement. Despite the significance of pattern in mind, constitutive relations or numerical models considering finite‐strain mechanical effects various patterns are rarely developed. In this paper, we propose novel 3D DEM modeling scheme by using coarse particles to represent sand grains and fines cementing agents, reproduce MICP‐treated sand. Based on...
Summary Large deformation soil behavior underpins the operation and performance for a wide range of key geotechnical structures needs to be properly considered in their modeling, analysis, design. The material point method (MPM) has gained increasing popularity recently over conventional numerical methods such as finite element (FEM) tackling large problems. In this study, we present novel hierarchical coupling scheme integrate MPM with discrete (DEM) multiscale modeling geomechanics. is...
Abstract In this paper, a new formulation of material point method (MPM) to model coupled soil deformation and pore fluid flow problems is presented within the framework theory porous media. The saturated medium assumed be consisting incompressible deformable skeleton made up solid grains. main difference proposed MPM algorithm implicit treatment pore‐water pressure which satisfies its incompressibility internal constraint. resulting solid‐fluid equations are solved by using splitting based...
ABSTRACT Granular flow is ubiquitous in various engineering scenarios, such as landslides, avalanches, and industrial processes. Reliable modeling of granular crucial for mitigating potential hazards optimizing process efficiency. However, the complex behavior media, which transitions between solid‐like fluid‐like states, poses a significant challenge their modeling, particularly when involving rapid mobilization. To address this challenge, we propose an innovative constitutive model capable...
Abstract Climate warming accelerates permafrost thawing, causing warming‐driven disasters like ground collapse and retrogressive thaw slump (RTS). These phenomena, involving intricate multiphysics interactions, phase transitions, nonlinear mechanical responses, fluid‐like deformations, pose increasing risks to geo‐infrastructures in cold regions. This study develops a thermo‐hydro‐mechanical (THM) coupled single‐point three‐phase material point method (MPM) simulate the time‐dependent...
Pullout of plate anchors from granular sands is investigated using a novel computational multiscale approach. We employ the material point method (MPM) to solve large deformation boundary value problem and adopt discrete element (DEM) derive history-dependent responses required for each MPM domain. The continuum-discrete hierarchical coupling between DEM not only helps bypass assumption complicated phenomenological constitutive models sand, but also facilitates handling displacement movement...

The proposed features rigorous coupling continuum‐based material point method (MPM) and discrete approach element (DEM) to enable cross‐scale boundary value problems pertaining media. It employs MPM solve the governing equations macroscopic continuum domain problem that may undergo large deformation. required loading‐path‐dependent constitutive responses...
Abstract This article presents a novel, scalable parallel computing framework for large‐scale and multiscale simulations of granular media. Key to the new is an innovative thread‐block‐wise representative volume element (RVE) parallelism, inspired by resemblance between typical computational hierarchy hierarchical thread structure graphics processing units (GPUs). To solve problem, all computation in RVE assigned single block threads so that runs entirely on GPU avoid frequent data exchange...
Abstract In this paper, a fully coupled thermo-hydro-mechanical material point method, applicable to liquid-saturated porous systems undergoing large deformations and phase transitions, is presented. A mathematical framework was established based on multiphasic mixture theory fundamental physical conservation laws, rather than using phenomenological or semi-empirical equations. fractional-step-based semi-implicit solution scheme proposed solve the formulations within of generalized...
In recent years, β-blockers such as metoprolol have been upgraded to first-line antihypertensive drugs. However, demonstrates poor prognosis effects on diseases stroke. Further clinical application may expand the possibility of its related adverse reactions. Currently, there is a lack comprehensive research overall safety metoprolol.
