Nanocrystalline (NC) metals and alloys are known to possess superior mechanical properties, e.g., strength, hardness, and wear-resistance, as compared to conventional microcrystalline materials. NC metals are characterized by a mean grain size <100 nm; in this grain size regime, inelastic deformation can occur via a combination of interface-mediated mechanisms viz., grain boundary sliding/migration, and dislocation nucleation from grain boundary sources. Recent studies have suggested that these interface-mediated inelastic deformation mechanisms in fcc metals are influenced by non-glide stress

Abstract:
This thesis presents how to establish a theoretical model to predict risk of thermal cracking in young concrete when cast on ground or an arbitrary construction. The crack risk in young concrete is determined in two steps: 1) calculation of temperature distribution within newly cast concrete and adjacent structure; 2) calculation of stresses caused by thermal and moisture (due to self-desiccation, if drying shrinkage not included) changes in the analyzed structure. If the stress reaches the tensile strength of the young concrete, one or several cracks will occur. The main focus of this work is

In such circumstances, the response of solids will often be highly non-linear, displaying elastic and plastic behaviour, and even moderate compressions will produce strong shock waves. This w

Дисертацію присвячено створенню нових методів опису та моделювання анізотропної в'язкопружності композиційних елементів конструкцій і машин. На підставі аналізу актуальних методик встановлено, що на даний момент не існує комплексного підходу до встановлення параметрів анізотропної в'язкопружності полімерних армованих композиційних матеріалів, а також моделювання їхньої механічної пове

Abstract:
This thesis describes the novel test techniques that were developed to measure the parameters associated with the plastic shrinkage, and subsequent possible plastic shrinkage cracking, of high strength concrete. The parameters measured during the first 24 hours after placing were the stress- strain relationship, negative pore pressure and free shrinkage strain development. The plastic behaviour of eight high strength concrete mixes was quantified and these mixes were then tested to assess their propensity towards plastic shrinkage cracking, using restrained ring tests.

O Brasil, à semelhança de outros países, está envelhecendo rapidamente. Os indivíduos com mais de 60 anos compõem hoje o segmento que mais cresce em termos proporcionais, mostrando um incremento da ordem de 500%, em 40 anos. A estimativa para o ano de 2020 é de que o Brasil tenha em torno de 32 milhões de indivíduos idosos, e desta população, uma parcela significativa será parcial ou totalmente desdentada, necessitando de aparelhos protéticos. Apesar da Odontologia apresentar avanços científicos notáveis na reabilitação da saúde bucal, muitos ainda usarão estes aparelhos. Sabe-se que o uso con

Abstract:
The strength of notched and impact damaged laminates was studied. The solution for a plate containing an elliptic opening and inclusion was used as given by Lekhnitskii. The solution for the infinite plate, combined with laminate analysis to determine the ply stresses, and the average stress criterion proposed by Whitney and Nuismer were used to predict the notched strength. However, unlike Whitney and Nuismer, the average stress criterion was used at the ply level. The strength of off-axis unidirectional laminates was predicted by using a matrix oriented failure criterion applied at a critic
