Η παρούσα εργασία ασχολείται με την ανάπτυξη, βαθμονόμηση και αριθμητική υλοποίηση ενός νέου ισότροπου, ελαστοπλαστικού, ανεξάρτητου του ρυθμού παραμόρφωσης (rate-independent) μοντέλου για πορώδη μεταλλικά υλικά. Γίνεται η υπόθεση ότι η μικροδομή αποτελείται από μια τυχαία (με ομοιόμορφη πιθανότητα) κατανομή σφαιροειδών πόρων ίδιου σχήματος αλλά με ...

Characterisation of porous materials for bioseparation
Journal of Chromatography A, 2009A set of chromatographic materials for bioseparation were characterised by various methods. Both commercial materials and new supports presenting various levels of rigidity were analysed. The methods included size-exclusion and capillary phenomena based techniques. Both batch exclusion and inverse size-exclusion chromatography were used. Gas adsorption,

Determination of Connectivity in Porous Materials
Journal of Nanoscience and Nanotechnology, 2012A method of practical use was set up to determine the connectivity in a porous material, modelling the physical system as a lattice, whose coordination number is assumed to be an index of connectivity itself. This task was approached through the theory of percolation and input data were provided by two different experimental techniques, that is ...

Realistic modeling of porous materials
Computer Animation and Virtual Worlds, 2016AbstractPhotorealistic modeling and rendering of materials with complex internal mesostructure is a hard challenge in Computer Graphics. In particular, macroscopic porous materials consist of complex translucent substances that exhibit different details and light interaction at several different scales.

Mechanical Properties of Porous Materials
Journal of Porous Materials, 1999Porous materials are commonly found in nature and as industrial materials such as wood, carbon, foams, ceramics and bricks. In order to use them effectively, their mechanical properties must be understood in relation to their micro-structures. This paper studies the mechanical properties of a few common porous materials: carbon rods, ceramics ...

Natural gas has received significant attention as a cleaner energy source alternative to gasoline. Natural gas consists of mainly methane (CH4); therefore, efficient storage of CH4 is essential to utilize natural gas. Porous materials have been widely used to store CH4 in a safe, efficient and cost-effective way. Among various different types of porous

Diffusion in porous crystalline materials
Chemical Society Reviews, 2012The design and development of many separation and catalytic process technologies require a proper quantitative description of diffusion of mixtures of guest molecules within porous crystalline materials. This tutorial review presents a unified, phenomenological description of diffusion inside meso- and micro-porous structures. In meso-porous materials,
