Multi-scale modelling of heterogeneous shell structures

2011

International audience; This paper reviews multi-scale computational homogenisation frameworks for the non-linear behaviour of heterogeneous thin planar shells. Based on a review of some of the currently available methods, a computational homogenisation scheme for shells is applied on to representative volume elements for plain weave composites. The effect of flexural loading on the potential failure modes of such materials is analysed, focusing on the reinforcement-matrix delamination mechanism. The attention is next shifted toward failure localisation in masonry unit cells. Subsequently, a recently developed computational FE2 solution scheme accounting for damage localisation at structura…

Organisaation sisäisten tilannetekijöiden vaikutukset tietojärjestelmien kehitysmenetelmien valintaan

2015

Tietojärjestelmien kehitysprojektit kohtaavat edelleen budjettiin, projektin keston venymiseen sekä järjestelmän laatuun liittyviä ongelmia. Tietojärjestelmiä kehitetään erilaisilla menetelmillä erilaisissa tilannetekijöiden muodostamissa konteksteissa. Osa edellä mainituista ongelmista liittyy tietyn menetelmän tai menetelmän osien huonosta soveltuvuudesta tiettyyn kontekstiin. Tämä tutkielma keskittyy tarkastelemaan organisaation sisäisiä tilannetekijöitä, joita ovat esimerkiksi projektin koko, organisaation kulttuuri, projektin tyyppi ja kehitystyön ulkoistaminen. Tutkielman tiedonkeruumenetelmänä käytetään kirjallisuuskatsausta. Tässä tutkielmassa pyritään selvittämään tarkasti ja laaja…

Biological invasions are recognized as a significant evolutionary factor over short time scales. In particular, their effect is well recorded on the genetic structure of populations, the patterns of phenotypic evolution and the richness of parasite fauna associated to invasive populations. This study aims at quantifying the consequences of a biological invasion according to these three levels (genetical, phenotypical and parasitological) taking as example the Mozambique tilapia Oreochromis mossambicus. This African cichlid is characterized by an unusual conservation status since it is both (i) ranked among the world's worst invasive species due to its global dispersion during the 20th centu…

Study of morphology, mechanical properties and thermal degradation of titania-polycarbonate nanocomposites as function of crystalline phase and amount

2013

Titania nanoparticles were prepared using a sol–gel method and calcination at 2008C and 6008C to obtain anatase and rutile phases, respectively. The obtained powders were used to prepare polycarbonate (PC)-titania nanocomposites by melt compounding. The effect of different crystalline phases and amounts of titania, in the range 1–5 wt%, on the morphology, mechanical properties, and thermal degradation kinetics of PC was investigated. The results show that the filler modified the plasticity or rigidity of the polymer and influenced the degradation kinetics, in different ways depending on the type and amount of titania.

New Insights into Segmental Packing, Chain Dynamics and Thermomechanical Performance of Aliphatic Polyurea Composites: Comparison between Silica Oxid…

2021

Polyurea (PU) is intrinsically reinforced by its microphase-separated morphology, giving its excellent mechanical properties. In this study, it is shown how a high-index PU formulation applies easy diffusion of hard segments into the soft phase of the PU matrix and tune its chain mobility. Moreover, the interaction of micro (>100 nm), nano (<100 nm) fillers with the microdomains and their thermomechanical properties are unraveled. Herein, nanosilica oxide (NS) and micro titanium (III) oxide (Ti2O3) are incorporated at low loadings into a solvent-free two-component aliphatic PU via insitu polymerization. While NS achieves an interfacial interaction with urea groups and forms a tight ha…

Sadutettu sanasto: puhutun kielen leksikaalinen diversiteetti arviointikohteena

 This study analyses lexical diversity (sums of probabilities) in spoken narratives of L1 and L2 school age children (n = 99) and compares the results to the lexical diversity of written narratives of the group of comparison. The key research questions are: a) does the lexical diversity of the spoken narratives systematically differ from the lexical diversity of written narratives and b) does the lexical diversity of spoken narratives systematically differ depending on five individual variables: lexical skills, language proficiency, L1 , gender and age of the speaker? All the narratives are produced in Finnish in storytelling events during the spring semester of the 2d a…

Confocal laser scanning microscopy for the study of the morphological changes of the postextraction sites

2012

A better understanding of the remodeling process of postextraction sockets is essential in dental treatment planning. The aim of this study was to evaluate whether confocal laser scanning microscopy (CLSM) can be applied to imaging contour changes of postextraction sites, as well as to its quantification with image analysis of obtained three-dimensional images. This work describes a new application of the CLSM technique. The system used was the OLS3100-USS, LEXT model (Olympus((R))). CLSM was used for the surface analysis of the extraction site. The measurements taken with CLSM were: (1) mesio-distal distance, (2) alveolar ridge thickness, and (3) vestibular and lingual alveolar ridge heigh…
