Failure analysis of quasi-brittle media using the micropolar continuum theory, elastic-degrading constitutive models, and smoothed point interpolation methods
(Universidade Federal de Minas GeraisUFMG, 2018-06-15)
The present thesis address the issue of localization (or discontinuous failure) in quasi-brittle materials modelled as elastic-degrading media, using two dierent regularization strategies, applied individually as well as ...
Multiscale design of elastic solids with biomimetic cancellous bone cellular microstructures
(Springer, 2019-02)
Natural (or biological) materials usually achieve outstanding mechanical performances. In particular, cancellous bone presents a high stiffness/strength to weight ratio, so its structure inspires the development of novel ...
High temperature mechanical behavior of porous cordierite-based ceramic materials evaluated using 3-point bending
(Elsevier, 2015-07-02)
Cordierite-based ceramics are an important segment of the present ceramic industry. In the last years, cordierite-based porous ceramics have received great attention as light structural materials, thermal insulting and ...
Application of ultrasonically modified cloud point extraction method for simultaneous enrichment of cadmium and lead in sera of different types of gallstone patients
(2017-11-01)
A novel and greener ultrasonically assisted/modified cloud point extraction procedure for the simultaneous preconcentration of lead and cadmium in serum samples of different types of gallstone patients was developed. The ...
Methods for qualitative analysis of cefazolin sodium raw material and pharmaceutical product
(Scientific and Academic Publishing, 2013)
In this work we studied qualitative methods for analysis and identification of cefazolin sodium, β-lactam antimicrobial for parenteral use, belonging to the group of first-generation cephalosporin, used as a therapeutic ...
Implementación del Método del Punto Material para aplicaciones geotécnicas bajo cargas estáticas
(Universidad Nacional de Colombia - Sede Bogotá, 2020-02-17)
Problems in Geotechnical Engineering are usually very complex due to the high non-linearity of the soil behaviour, the interaction with different structures, and the large deformations of the soil mass. Therefore, simulating ...
