Benchmark Simulations of Dense Suspensions Flow Using Computational Fluid Dynamics
Frontiers in Materials, 2022 The modeling of fresh concrete flow is still very challenging. Nevertheless, it is of highest relevance to simulate these industrially important materials with sufficient accuracy. Often, fresh concrete is assumed to show a Bingham-behavior. In numerical

A Phantom-Node Method with Edge-Based Strain Smoothing for Linear Elastic Fracture Mechanics
Journal of Applied Mathematics, 2013 This paper presents a novel numerical procedure based on the combination of an edge-based smoothed finite element (ES-FEM) with a phantom-node method for 2D linear elastic fracture mechanics. In the standard phantom-node method, the cracks are formulated

Derivation of SPH equations in a moving referential coordinate system [PDF]
, 2009 The conventional SPH method uses kernel interpolation to derive the spatial semi-discretisation of the governing equations. These equations, derived using a straight application of the kernel interpolation method, are not used in practice. Instead the
