ARQUITECTURA Y EVANGELIZACIÓN
(2021-10-23)
Bajo la perspectiva simbólica y la interpretación formulada desde planos sincréticos que aún se pueden identificar, los templos cristianos levantados entre los siglos XVI y XVII en el Cusco exponen bajo sus espacios, formas y elementos propios de la evangelización, connotaciones míticas y contenidos que los vinculan con los antiguos adoratorios Inkas sobre los cuales fueron construidos, testificando la vigencia de la cultura andina ancestral pese a los procesos de extirpación de idolatrías activados desde el ...

Parameter identification of crack-like notches in aluminum plates based on strain gauge data
(2020-12-31)
The identification of crack parameters and stress intensity factors in aluminum plates under tensile loading is in the focus of the presented research. In this regard, data of strain gauges, distributed along the edges of the samples, are interpreted. In the experiments, slit-shaped notches take the role of cracks located in the interior of the specimens. Their positions, inclinations and lengths as well as the magnitudes of external loadings are identified solving the inverse problems of cracked plates and associated ...

Quenching of High Entropy Alloys after Annealing
(2020)
The effect of cooling rate after annealing at 900 °C on the microstructure and hardness of high entropy alloys was investigated using two typical samples with the chemical composition of Co₁₆Cr₁₄.₅Fe₂₉Mn₁₁.₅Ni₂₉ and Co₁₁.₅Cr₇Fe₂₇Mn₂₇Ni₂₇(Nb₀.₀₈C₀.₅) (at%). The microstructural characterisation and hardness measurements were carried out by optical microscopy, scanning electron microscopy, wavelength-dispersive X-ray spectroscopy, electron back scattered diffraction, X-ray diffraction technique and Vickers hardness ...

On the reliability of residual stress measurements in unidirectional carbon fibre reinforced epoxy composites
(2021-03-03)
The present work introduces a novel methodology to analyse non-uniform residual stresses in composite materials. For robust determination of stresses in complex structures made of different layers, it is first necessary to prove that residual stress analysis in a single layer structure can reliably be accomplished. In present work a unidirectional carbon fibre reinforced epoxy is investigated. For residual stress determination, the integral incremental hole drilling method is used. It is revealed that the standard ...

On the influence of build orientation on properties of friction stir welded AleSi10Mg parts produced by selective laser melting
(2021-04-06)
Welding and joining of components processed by additive manufacturing (AM) to other AM as well as conventionally produced components is of high importance for industry as this allows to combine advantages of either technique and to produce large-scale structures, respectively. One of the key influencing factors with respect to weldability and mechanical properties of AM components was found to be the inherent microstructural anisotropy of these components. In present work, the precipitation-hardenable Al–Si10Mg was ...

Effect of Grain Statistics on Micromechanical Modeling: The Example of Additively Manufactured Materials Examined by Electron Backscatter Diffraction
(2020-02-21)
Micromechanical modeling is one of the prominent numerical tools for the prediction of mechanical properties and the understanding of deformation mechanisms of metals. As input parameters, it uses data obtained from microstructure characterization techniques, among which the electron backscatter diffraction (EBSD) technique allows us to understand the nature of microstructural features, that are usually described by statistics. Because of these advantages, the EBSD dataset is widely used for synthetic microstructure ...

Effect of Tool Temperature on Mechanical Properties and Microstructure of Thermo-Mechanically Processed AA6082 and AA7075 Aluminum Alloys
(2020-06-08)
The present work focuses on the effect of thermo-mechanical processing on the mechanical properties and microstructural evolution of AA6082 and AA7075 aluminum alloys using a novel forming process, i. e. integrating solution heat treatment, hot forming and tool quenching. Different tool temperatures ranging from 24 °C to 350 °C were applied to investigate their influence on mechanical strength and ductility. By using various tool temperatures, this study aims to provide insights needed for tailoring the mechanical ...

50 AÑOS HACIENDO, ENSEÑANDO Y COMENTANDO ARQUITECTURA EN EL PERÚ
(2020-10-17)
"No es tarea fácil resumir en el tiempo disponible la amplia y larga vida profesional que he ejercido con Antonio Graña y Eugenio Nicolini. Complica más la tarea, el hecho de que ella haya estado imbricada con una dedicación académica y una actividad periodística también muy exigentes. A ello, tendría que añadir mi incursión en política y la actividad museográfica, todo lo cual he ejercido con una simultaneidad persistente.
Procuraré por tanto mostrar una fracción de los más de 450 proyectos desarrollados por nuestro ...
