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...

ویژگی های زمین شیمیایی، کانی شناسی، و میکرومورفولوژیکی خاک ها و سنگ مادر مربوطه در منطقه بین بخش های جنوبی زاگرس و خلیج فارس تا دریای عمان(استان هرمزگان، ایران) مورد بررسی قرار گرفت. هدف های این مطالعه شناسایی تغییرات در خصوصیات فیزیکی، شیمیایی، و ترکیب کانی شناسی خاک، مطالعه میکرومورفولوژی و تکامل خاک، و بررسی توزیع عنصر خاک بر اساس هوازدگی، پروسه های خاک و زمین شناسی جهت توصیف اثرات مواد مادر...
15 صفحه اولDauphiné twinning in polycrystalline quartz
A recently developed crystal based continuum model for twinning and phase transformations is successfully applied to Dauphiné twinning and the α (trigonal) ↔ β (hexagonal) phase transformation in quartz. Both finite element and uniform deformation simulations are performed of quartz polycrystals and several experimentally observed phenomena are qualitatively reproduced. Results are given for me...
متن کاملAcoustic Emission of Deformation Twinning in Magnesium
The Acoustic Emission of deformation twinning in Magnesium is investigated in this article. Single crystal testing with combined full field deformation measurements, as well as polycrystalline testing inside the scanning electron microscope with simultaneous monitoring of texture evolution and twin nucleation were compared to testing at the laboratory scale with respect to recordings of Acousti...
