Generation of porous particle structures using the void expansion method
The newly developed “void expansion method” allows for an efficient generation of porous packings of spherical particles over a wide range of volume fractions using the discrete element method. Particles are randomly placed under addition of much smaller “void-particles”. Then, the void-particle radius is increased repeatedly, thereby rearranging the structural particles until formation of a de...
متن کاملMaterial Computation
257 Material Computation therefore directly linked to the influences of force acting upon it. Material is concentrated in regions of high strength and dispersed in areas where stiffness is not required. The implications of Nature’s structural heterogeneity, achieved through the informed distribution of composites, holds significant implications from a design perspective. The control of material...
متن کاملAnalysis and Optimization of Void Spaces in Single Ply Raw Material using Finite Element Method and Fused Deposition Modelling
Fused Deposition modelling (FDM) technology is based on decomposition of 3-D computer models into thin cross sectional layers, followed by physically forming the layer and stacking them up layer by layer. FDM provide freedom to add material in the desired area and we are also able to create hollow region in certain portion of layer. In this way low weight with good strength single ply raw mater...
متن کاملA fed back level - set method for moving material – void interfaces 1
This report is a feasibility study of a level-set method for the computation of moving material–void interfaces in an Eulerian formulation. The report brie y introduces level-set methods and focuses on the development of such a method, that does not just accurately resolve the geometry of the interface, but also the physical quantities at and near the interface. Results are presented for illust...
