For the numerical simulation in continuum mechanics the Composite Finite Element (CFE) method allows an effective treatment of problems where material parameters are discontinuous across geometrically complicated interfaces. Instead of complicated and computationally expensive tetrahedral meshing, specialized CFE basis functions are constructed on a uniform hexahedral grid. This is a convenient...

A novel unit cell structure with re-entrant hollow skeleton is designed and its Poisson's ratio has been studied using the finite element method (FEM) as a function of the geometric variables and the parent material Poisson's ratio. The simulation results showed that the Poisson's ratio of the unit cell structure is tunable over the full range of Poisson’s ratio (-1 to +0.5) by varying the geom...

— This paper presents a magnetic circuit modeling of closed loop Hall-effect current sensors based on a magnetic equivalent circuit which could be simulated with a circuit type simulator software (PSPICE model). First, the principle of measurement of the closed loop Hall-effect current sensors is presented, Then, the magnetic equivalent circuit (MEC) modeling justified by the engineers' model n...

Abstract This work presents a meshfree particle scheme designed for arbitrary deformations that possess the accuracy and properties of Finite-Element-Method. The is maintained even with distributions. Mesh-based methods mostly fail if requirements on location evaluation points are not satisfied. Hence, this new only range loadings can be increased but also pre-processing step facilitated compar...

SLAC performs large-scale simulations for the next-generation accelerator design using higher-order finite elements. This method requires using valid curved meshes and adaptive mesh refinement in complex 3D curved domains to achieve its fast rate of convergence. ITAPS has developed a procedure to address those mesh requirements to enable petascale electromagnetic accelerator simulations by SLAC...

In order to simulate the mechanical behavior of large structures assembled from thin composite panels, we propose a coupling technique which substitutes local 3D models for the global plate model in the critical zones where plate modeling is inadequate. The transition from 3D to 2D is based on stress and displacement distributions associated with Saint-Venant problems which are precalculated au...

Human body 3D scanners are becoming a mature technology that generates accurate static photo-realistic 3D models of real human beings. However the data collected allow only the construction of the outer surface of the body. In this paper we describe how from 3D surface data we generate 3D volumetric meshes of soft tissues suitable for the finite element method (FEM). We then deform these meshes...
