Procédé multiéchelle pour la reconstruction des courbes d'émission acoustique révélatrices des ruptures de fibres au sein d'un composite unidirection…
2006
International audience; Dans cette étude, la première partie du travail consiste en une analyse fine, par éléments finis, des mécanismes de report de charge entre lesfibres rompues et intactes d'un composite unidirectionnel. On considère différentes configurations d'endommagement du composite et deux types de comportement matriciel (élastique et viscoélastique) avec ou sans décohésion à l'interface fibre rompue/matrice. En raison de ces différents aspects, les limites habituelles des approches faites jusqu'à présent sont repoussées et notamment celles des modèles analytiques. La seconde partie du travail consiste en la mise en place d'un procédé multiéchelles qui synthétise les phénomènes m…
Dissemination/Communication Plan. Period concerning the plan: 01.01.2018-31.12.2020.
2018
The plan concerning different dissemination/communication activities during three years of the project implementation is given. Scientific results are proposed to be disseminated in well-recognized bi-annual international conferences, such as European Conference on Composite Materials (ECCM) and International Conference on Composite Materials (ICCM). Self-archiving of the main project results is planned within subject-based open-access repositories, such as ResearchGate and Zenodo. Two scientific publications in Q1-Q2 SCI journals and two popular scientific publications in popular scientific Latvian journals are foreseen. All data files obtained within the project are to be stored in centra…
Google Sites rīka izmantošana starppriekšmetu projektos fizikā un informātikā
2016
Darba mērķis ir, izmantojot rīka Google Sites iespējas mājas lapu veidošanā, izpētīt, vai, realizējot starppriekšmetu projektus, tiek veicināta skolēnu zināšanu un prasmju pilnveide fizikā un informātikā. Darbā tika apkopota un analizēta zinātniskā un metodiskā literatūra par projektu metodi un starppriekšmetu saikni. Tika izveidoti 7 un aprobēti 2 projekta darbi starppriekšmetu saiknes realizēšanai fizikā un informātikā, kā arī izvērtēta to ietekme uz skolēnu zināšanām un prasmju pilnveidi fizikā un informātikā. Starppriekšmetu projektu darbi veicina skolēnu zināšanu un prasmju pilnveidi, attīsta sadarbības prasmes, paaugstina motivācijas līmeni vairumam skolēnu. Darbā ir 84 lappuses, 28 a…

A methodology for the control of the residual lifetimes of carbon fibre reinforced composite pressure vessels
2005
International audience; Pressure vessels must be periodically proof tested. Traditional techniques for metal vessels are inapplicable for composite vessels as the latter do not break by crack propagation so that the reasoning behind the traditional testing procedures is not appropriate. Damage accumulation leading to the degradation of a composite vessel is by fibre failure. Fibres show a wide distribution in strengths and loading a composite inevitably breaks some. The method which has been developed is supported by an analysis of delayed fibre failure due to the relaxation of the resin around fibre breaks. This provokes overloading of intact fibres neighbouring breaks. The time until a cr…
Antifouling Mortars for Underwater Restoration
2022
This research has focused on the assessment of the compositional features and mechanical and antifouling performances of two different mortars formulated for an underwater setting, and which contain Mg(OH)2 as an antifouling agent. Regarding the mechanical characterization, the uniaxial compressive strength and flexural strength were measured. The composition of the materials was explored by differential thermal/thermogravimetric analysis (DTA-TG), X-ray diffraction analysis (XRPD), and scanning electronic microscopy (SEM) coupled with EDS microanalysis. The assessment of the biological colonization was evaluated with colorimetric analysis and image analysis. The results suggest that both m…
La Reggia di Venaria Reale in Italy and Palacio Real de Aranjuez in Spain: history, restoration and significance, comparative study between Two Royal…
2017
La investigación relaciona dos sitios reales, La Reggia di Venaria Reale en Italia y el Palacio Real de Aranjuez en España, confrontando su desarrollo histórico y arquitectónico, las obras de restauración llevadas a cabo, los criterios para su inclusión en la Lista de Patrimonio Mundial y su uso hoy en día como museos. El estudio comparativo muestra cómo ambos palacios se usaban inicialmente como residencias de caza en lugares con abundancia de agua y pesca. Además, los dos están ubicados cerca de las capitales políticas de su tiempo; esto es, Turín y Madrid. El hecho que el mismo arquitecto – Filippo Juvarra estuviera presente en ambas residencias reales contribuye a las similitudes, y en …
Room temperature synthesis of lanthanum phosphates with controlled nanotexture as host for Ln(III) through the Epoxide Route
2022
AbstractHerein, the Epoxide Route, a one-pot room temperature alkalinization method based on the reaction between a nucleophile and an epoxide, has been employed to synthesize LaPO4 in the form of a Rhabdophane phase. The intrinsic features of this synthetic approach allow the reaction to be followed by pH monitoring, making possible the identification of the different precipitation steps involved in the formation of the solid. Once demonstrated the effectiveness of this chemical methodology, the size and shape of the LaPO4 particles were controlled by varying the identity and proportion of the organic co-solvents employed to perform the reaction. By these means, crystalline particles with …
