Numerical micromechanical modelling of brittle polycrystalline materials
A generally applicable framework for generating a nite element mesh that is based on the actual micro-structure of a material is developed. The procedure is applied to a microscopic image of a ceramic material. Special attention is paid to the modelling of the interfaces between adjoining grains. Plane strain and plane stress nite element calculations are performed. The observed e ective consta...
متن کاملDevelopments in micromechanical modelling of granular materials
We are honouring the memory of Ioannis Vardoulakis through this special issue of Granular Matter, which is devoted to developments in micromechanical modelling of granular materials. Ioannis Vardoulakis will be forever remembered as an innovative experimentalist, a brilliantmechanician, an enthusiastic scientist, a devoted teacher, and above all an exceptional human being. The impression he mad...
متن کاملSynthesis of syntactic steel foam using gravity-fed infiltration
In this study, we report a procedure for producing syntactic steel foams by melt infiltration of millimeter-sized ceramic microspheres. The gravity-fed infiltration method yields steel foam with uniform distributions of microspheres and negligible unintended porosity. The critical parameters in the manufacturing process are the melt temperature and the preheat temperature of the microspheres pr...
متن کاملSynthesis of syntactic steel foam using mechanical pressure infiltration
Steel foam offers potential advantages over aluminum foams and other metallic foams. The inherent strength of steel combined with the reduced density of foam presents an attractive material with greater strength and modulus than light alloy foams, greatly reduced density relative to solid steel, and efficient energy absorption. However, thus far there have been few reports describing efforts to...
متن کاملCompression and low-velocity impact behavior of aluminum syntactic foam
We report quasi-static compression and impact behavior of aluminum syntactic foams (ASF) produced by melt infiltration. Aluminum syntactic foams with relative density of 0.46 were produced using hollow alumina spheres (4.45 mm and 3.05 mm) randomly situated in a mold and two types of aluminum alloy (1100 and 6061). The impact behavior was investigated using an instrumented drop tower. We invest...
