1. Role of multi-layer pyramidal truss cores as an inner material of energy absorbing structures
Abstract In this study, finite element analysis was performed to investigate the feasibility of multi-layered pyramidal truss structures as a filler material of energy absorbing tubes. Rectangular tubes with the filler and empty tubes were compressed at a constant velocity of 10km/h and their energy absorbing capabilities were compared to demonstrate the str

3. Estimación de propiedades mecánicas de chapa de acero inoxidable 304L mediante ensayos SPT
ABSTRACT The mechanical characterization of materials by small specimen testing has growing interest in Structural Engineering. Small Punch Test (SPT) is applied to estimate mechanical properties of samples that can be extracted from components or structures without affecting service operation. In this paper the development of the test device is reported, co

4. Theoretical Approach to Simulate Efficient Selective Solar Absorbers With Micro or Nano Structured Arrays
Study of the solar absorber with photonic crystal or micro structures as the heat absorbing surfaces operated at a high-temperature was conducted. Numerical calculations based on rigorous coupled-wave analysis were performed to determine the absorptance of the photonic crystal surface on the absorber. The effect of nano geometry of the photonic crystal in tu

5. Characterization of the Austenite Reformation Mechanisms as a Function of the Initial Ferritic State in a UNS S32304 Duplex Stainless Steel
Aiming to better understand the effects of heat treatment parameters on Ferrite-Austenite phase transformation in a 2304 duplex stainless steel different thermal cycles were applied to this steel in a quenching dilatometer. The obtained microstructures were characterized by optical microscopy, transmission electron microscopy and electron backscatter diffrac

6. Growth, viability and architecture of biofilms of Listeria monocytogenes formed on abiotic surfaces
Abstract The pathogenic bacterium Listeria monocytogenes can persist in food processing plants for many years, even when appropriate hygienic measures are in place, with potential for contaminating ready-to-eat products and, its ability to form biofilms on abiotic surfaces certainly contributes for the environmental persistence. In this research, L. monocyto

7. Microstructural behavior of SAF 2205 Duplex Stainless Steel Welded by Friction Hydro Pillar Processing
Abstract The Friction Hydro-Pillar Process (FHPP) is an innovative process that has been recently studied regarding its possible in situ repair applications. There is still no literature about usage of the FHPP on duplex stainless steel (DSS) base materials to smaller forces than 25 kN. The investigation on DSS processing is crucial due his wide variety of c

8. BIOFILM FORMATION OF Vibrio cholerae ON STAINLESS STEEL USED IN FOOD PROCESSING
Vibrio cholerae represents a significant threat to human health in developing countries. This pathogen forms biofilms which favors its attachment to surfaces and its survival and transmission by water or food. This work evaluated the in vitro biofilm formation of V. cholerae isolated from clinical and environmental sources on stainless steel of the type used

9. Hausdorff Distance evaluation of orthodontic accessories' streaking artifacts in 3D model superimposition
The aim of this study was to determine whether image artifacts caused by orthodontic metal accessories interfere with the accuracy of 3D CBCT model superimposition. A human dry skull was subjected three times to a CBCT scan: at first without orthodontic brackets (T1), then with stainless steel brackets bonded without (T2) and with orthodontic arch wires (T3)

10. Linear dimensional changes in plaster die models using different elastomeric materials
Dental impression is an important step in the preparation of prostheses since it provides the reproduction of anatomic and surface details of teeth and adjacent structures. The objective of this study was to evaluate the linear dimensional alterations in gypsum dies obtained with different elastomeric materials, using a resin coping impression technique with

11. Modificação e caracterização da superfície do aço inoxidável Martensítico AISI 410 / Surface modification and characterization of the AISI 410 Martensitic stainless steel
This work deals about the surface modification of the AISI 410 martensitic stainless steel. The modification of steel surfaces is important for the improvement of its mechanical and tribological properties. Among the modification processes, there are coating, deposition of thin films, and ion implantation. The AISI 410 stainless steel is widely applied by ma

12. Processing of a duplex stainless steel by equal channel angular extrusion
A UNS S32205 duplex stainless steel was processed by ECAE in three different velocities, at room temperature, and heat treated in different temperatures and times to evaluate recrystallization. Attrition forces promoted great deformation heterogeneity in the samples sections, with hardness increase, and morphology changes in the grains and changing orientati
