Finite Element Simulation using SPH Particles as Loading on Typical Light Armoured VehiclesLight Armoured Vehicles (LAV) are essential to transport troops and equipment in combat and high risk zones. The emergence of non conventional threats such as Improvised Explosive Devices (IED) implies a need ...

For computational continuum dynamics, as alternatives to conventional mesh-based methods, e.g. finite element method (FEM) and finite volume method (FVM), meshless methods have flourished in the past decades [1], [2], [3], [4]. Smoothed particle hydrodynamics (SPH), initially developed by ...
This paper presents a simple technique to couple the Finite Element Method (FEM) and the Smooth Particle Hydrodynamics Method (SPH) in the Lagrangian framework for the simulation of problems involving solids and structures under shock loading that cause large deformations, such as rock blasting. For...
The potential fracture domains of the flexible body system are described by using the particles of smoothed particle hydrodynamics (SPH), and the other domains of the system are modeled by using the finite elements of absolute nodal coordinate formulation (ANCF). In order to preserve the ...
(BEM), extended finite element method (X-FEM), discontinuous deformation analysis (DDA), finite cover method (FCM), Peridynamics (PD), discrete element method (DEM), smoothed particle hydrodynamics (SPH), material point method (MPM), etc., among others) have seen wide introduction in ...
The smoothed particle hydrodynamics (SPH) and the finite element method (FEM) are used, respectively, for modeling the fluid and solid phases. A range of pressure differences and membrane thicknesses are studied and two different rupturing processes are identified. These processes differ in the ...
where the superscripts n and ∗ refer to the field quantities at t n and the temporary time step, respectively. After the temporary field quantities are derived, the time derivative at t n can be evaluated after reconstructing the particles along every vertical line. The numerical process can...
micrometres along the fibre direction, while the element size in the plane perpendicular to the fibre axis varied depending on the part’s geometry. An SPH particle was added at the centre of each finite element. Tie constraints were imposed between the FE elements and the SPH particles to ...
