In this study, we investigate if finite element (FE) analyses of human trabecular bone architecture based on 168 microm images can provide relevant information about the bone mechanical characteristics. Three human trabecular bone samples, one taken from the femoral head, one from the iliac crest, and one from the lumbar spine, were imaged with micro-computed tomography (micro-CT) using a 28 mi...

The nite element method is being used today to model component assemblies in a wide variety of application areas, including structural mechanics, uid simulations, and others. Generating hexahedral meshes for these assemblies usually requires the use of geometry decomposition, with di erent meshing algorithms applied to di erent regions. While the primary motivation for this approach remains the...

Meshing tools are extremely complex pieces of software. Traditionally, they have been built in a one by one basis, without systematically reusing already developed parts. The area has matured so that we can currently think of building meshing tools in a more industrial manner. Software product lines is a trend in software development that promotes systematic reuse. We propose a layered product ...

Isometric modification is proposed as a new method of axial modification of spur bevel gear. Based on the gear geometry theory and the normal meshing motion equation of gear pairs, changes of meshing points and angles are analyzed and the effect of axial modification on meshing movement of gear pairs is discussed. After that, a method of drawing spherical involute with the aid of SolidWorks sof...

A unified topological layer for mesh generation has been created to benefit from current development, to reuse existing, well tested and reliable methods, such as the Delaunay or the Advancing Front mesh generation approach, and to combine them to be able to interchange these methods, without taking a detour using file formats. In addition, by modularizing existing meshing kernels, this approac...

Tread wear appears as a consequence of friction, which mainly depends on surface characteristics, contact pressure, slip velocity, temperature and dissipative material properties the tread itself. The subsequent description introduces model function frictional energy rate. A post-processing well an adaptive re-meshing algorithm are implemented into finite element code in order to predict loss t...

This paper proposes a practical, topologically robust and ranging error resistive shape modeling procedure that approximates a real 3D object with the matrix-formatted organized meshing for the 3D shape processing. A geometric model with desired meshing, not limited to triangular one, but also quadrilateral, hexagonal or n-gonal mesh, is directly reconstructed based on a solid modeling approach...

The objective of this note is to demonstrate the necessity of using an appropriate automatic adaptive meshing technique so as to handle complex microstructural evolutions. Examples of such microstructural evolutions include the deformation and recrystallization of polycrystalline aggregates or the growth of dendrites occurring during the solidification of metallic alloys. In such applications, ...
