Abstract:
Abstract In this study, we explored the stability and compactness of columns formed from highly irregular particles. These particles, known as Platonic polypods, are fashioned by extruding arms onto the faces of Platonic solids, for which we systematically varied the number and thickness of these arms. We investigated the emergence and vanishing of geometric cohesion (i.e., solid-like characteristics, in the absence of adhesive forces among particles). We first built columns by depositing particles within a cylindrical container, which was then removed to assess the structure’s stability. Expe

Abstract:
The discrete element method (DEM) has become the numerical method of choice for analysing and predicting the behaviour of granular materials in bulk handling systems. Wet-and-sticky materials (WSM) are especially problematic, resulting in build-up and blockages. Furthermore, due to the large number of particles in industrial-scale applications, it is essential to decrease the number of particles in the model by increasing their size (upscaling or coarse graining). In this study, the accuracy with which upscaled DEM particles can model the discharge of a cohesive material from a belt conveyor o

This paper presents numerical simulation and analysis of two numerical experiments of wet soil granular flow down inclined chutes based on the JKR(Johnson-Kendall-Roberts)-cohesion model of the discrete element method.

La résistance au cisaillement dans les matériaux granulaires s'explique souvent à l'aide du critère de rupture de Mohr-Coulomb. Ce critère repose sur deux paramètres clés : l'angle de frottement interne et la cohésion. L'angle de frottement interne est généralement lié à la rugosité et à la forme des particules, tandis que la cohésion est associée aux forces d'adhérence agissant entre les grains. Des recherches récentes ont introduit un nouveau domaine d'étude, mettant l'accent sur le potentiel des effets cohésifs dans les matériaux granulaires, sans nécessiter de forces d'adhérence.

While modalities relate directly to the philosophical concerns of metaphysicians, it has been recognized recently by mathematicians that operators behaving similarly can be deployed to capture spatial concepts synthetically.

In simplest terms, the points of a space are held together cohesively. Combining the spatial modalities with the refined notion of identity is just what is needed in cu

Abstract The plasma spray process is unique because the coating properties depend indirectly on the processing parameters. Therefore, the in-service properties derive mostly from the coating architecture. The coating architecture is related to the intrinsic lamellae formation mechanism; which is related to the impinging particle characteristics that are linked to the power and feedstock injection. The coating architecture is also related to the extrinsic spray pattern formation mechanism; i.e., the kinematics and geometric spray parameters such as spray velocity, spray angle, and stand off dis

Abstract:
Flow of particles is analyzed by considering driving force from applied shear energy (rotating augers). against constraints of extrinsic constraints (consolidation, boundary) and intrinsic constraints (cohesion, compressibility and inter-particle forces). Both Discrete Element Method (DEM) and Continuum Models are used to analyze powder flow with DEM uses models at particle level and is therefore requires costly computation where as Continuum Models are less accurate for complicated geometries and free surfaces. The cohesive (tensile) stress for an assembly of cohesive particles is an increasi

Abstract The Tazhong paleo-uplift is one of the most important hydrocarbon enrichment areas in Tarim Basin. After years of exploration, many reservoirs have been discovered in the deep Paleozoic carbonate karsted rocks. Current research suggests that tectonic evolution and faulting movements have an important impact on reservoir development and hydrocarbon accumulation. But the reservoir prediction reliability is greatly compromised due to the lack of appropriate technical means to ascertain the geometric and kinematic characteristics of fault system more accurately. We solve this difficulty t

Abstract:
Abstract The performance and health of logging while drilling (LWD) tools can be significantly impacted by the drilling dynamics of the bottomhole assembly (BHA). With drilling dynamics becoming increasingly harsh, BHA whirl is one of the undesired motions the tool can face during drilling operations, where the BHA follows an eccentric rotation about a point along the wellbore other than the geometric center. For example, parasitic motion that causes a plethora of distortions to the echo train, at times manifesting as erratic noise or a complete loss of cohesion has been a measurement quality

Abstract:
A significant amount of information generated during design and manufacturing contains textual and geometric descriptions such as CAD drawings. Solely text-based or geometry-based approaches have been prevalent in current engineering information retrieval techniques. In order to further enhance the retrieval performance and provide more cohesive engineering search environment, we developed a unified framework that combines text-based and geometry-based approaches. On the text side, we present a novel engineering ontology based retrieval that takes drawing annotations as input data. On the geom

Abstract:
Abstract Cohesive elements are fundamental in fracture mechanics, enabling accurate simulations of interfaces and offering critical insights into material behavior under diverse loading conditions. These elements employ traction-separation laws to model the transition of interfaces from an intact state to full separation, providing a detailed understanding of fracture processes. Traditional cohesive models often assume zero-thickness interfaces, a simplification that is inadequate when interface thickness, material properties, and geometry significantly influence stress distribution and deform

In this paper, we focus on distributed cohesive motion control of 3-dimensional multi-vehicle systems considering individual agent dynamic behaviors as well as the overall multi-vehicle system. In this context, we examine maintenance of geometric formation of a swarm of autonomous quadrotor vehicles, i.e. maintenance of the distance between each agent pair in the swarm, during arbitrary maneuvers. A distributed scheme for the formation maintenance task is developed first. This coordination scheme is integrated with low level dynamic controllers designed for the agents considering practical kin

This program contributes to maintaining and improving the integrity and safety of existing pipelines with regard to ground movement hazards, and reducing the capital costs of new pipeline systems. The research program focused on the axial, lateral and complex loading of pipeline due to soil movements. It includes (1) a literature review: it presents significant issues related to modeling pipe-soil interaction with a focus to recent development since ASCE (1984); (2) axial loading: it includes a summary of the methods to estimate the axial soil forces on pipeline and recent field measurements o
