Simulation of shear bands with Soft PARticle Code (SPARC) and FE

The aim of this paper is to numerically investigate the development, thickness and orientation of shear bands, in biaxial test with two approaches towards solving problems of continuum mechanics, namely the meshless "Soft PARticle" method and the mesh based Finite Element method. Soft PArticle Code (SPARC) is a straightforward collocation numerical method based on strong formulation, in which a...

Simulation of shear bands using polygonal particles

The choice of particle shape representation is critical in the accuracy of the simulations of real granular materials. Here we present a method to simulate particle shape using polygonal particles. The method reproduces shear bands using different boundary conditions: confining walls, floppy boundaries and periodic boundary conditions.

Application of Nano-Contact Mechanics Models in Manipulation of Biological Nano-Particle: FE Simulation

Contact mechanics is related to the deformation study of solids that meet each other at one or more points. The physical and mathematical formulation of the problem is established upon the mechanics of materials and continuum mechanics and focuses on computations involving bodies with different characteristics in static or dynamic contact. Contact mechanics gives essential information for the s...

Fabrication of Soft Magnetic Fe-based Nanoalloy

The Fe-Ni-Sb-B amorphous alloy has been prepared by a solid-solid chemical reaction of ferric trichloride, nickel chloride, antimony chloride and potassium borohydride powders at room temperature. The inductive couple plasma study indicates that the resultant is composed of Fe 5.38 %, Ni 56.19 %, Sb 29.02 % and B 0.44 %. The XRD and thermal analysis show that the alloy is a non-strict sense amo...
