Controlabilidade no interior para um sistema elástico e para um sistema termoelástico
(Universidade Estadual de MaringáPato BrancoBrasilPrograma de Pós-Graduação em MatemáticaUEM, 2017-08-25)
In this work, we analyze the internal exact controllability for an elastic linear system and the internal exact-approximate controllability for an thermoelastic linear system, both with vector components. In both cases, ...
Effect of the precipitates on the thermodynamics of the martensitic transformations in Ti-rich Ni-Ti-Co thin films
(Elsevier Science, 2020-03)
The wide-spread multiple transformation in Ti-rich Ni-Ti shape memory alloys produced by Ti2Ni nano-precipitates was investigated. For this purpose, a series of amorphous Ti-Ni-Co thin films with the same composition were ...

Quasiharmonic elastic constants corrected for deviatoric thermal stresses
(AMER PHYSICAL SOC, 2008)
The quasiharmonic approximation (QHA), in its simplest form also called the statically constrained (SC) QHA, has been shown to be a straightforward method to compute thermoelastic properties of crystals. Recently we showed ...
Determinação de soluções explícitas para o problema termoelástico não-estático
(2007-04)
Esta dissertação apresenta soluções explícitas para o problema termoelástico linear e isotrópico com base no método clássico de simetrias criado pelo matemática Sophus Lie. Para o cálculo destas soluções, apresentamos os ...
Thermally Induced Long-Term Displacement of Thermoactive Piles
(ASCE, 2014)
The long-term displacement of thermoactive piles subjected to static load and thermal cycles is analyzed using the numerical solution
of the one-dimensional load-transfer method modified to account for thermoelastic ...
Nonuniform laminated beam of Lord–Shulman type
(John Wiley and Sons IncGB, 2022)
The nonuniform thermoelastic laminated beam of the Lord–Shulman type is considered. The model is a two-layered beam with structural damping due to the interfacial slip. The well-posedness is proved by the semigroup theory ...
Contribución a la caracterización térmica de materiales con la técnica del alambre caliente (líquidos, gases y sus mezclas) y fotoacústica
(2015-11-03)
En este trabajo se presentan metodologías experimentales y de análisis y procesamiento de la información para la caracterización térmica de líquidos y sólidos. En el primer caso se propuso un modelo que describe la ...
