1. 3D Simulation and Artificial Neural Networks Application in the Diffusion Study of Champignon Mushroom/Solution Interface During the Salting
The influence of the film formed during the salting of champignon mushrooms with brine containing NaCl and KCl was modeled using the finite elements method (FEM). It was verified that the film formed on the mushroom surface had a greater influence in the static salting since the diffusion of the ions was 7.5-fold smaller in this system than in the stirred sa

2. Vibration control device for steel tubular towers of Horizontal Axis Wind Turbines
Abstract This paper presents and discusses the design of a vibration control device for a 120 m high steel tubular tower of onshore Horizontal Axis Wind Turbine (HAWT). The tower is modeled using beam (own code), and shell and solid finite elements (via ANSYS). The Dynamic Vibration Absorber (DVA) is designed to be attached to the tower top, aiming to analyz

3. The Search for the Centre of Resistance of a Tooth Using a Finite Element Model and the Continuum Mechanics
Abstract In orthodontics, the CR is defined as the ideal point for the positioning of the bracket. This paper presents numerical analyses of a premolar tooth, which aim at searching the centre of resistance (CR) by applying several external torques. We built the geometry of the tooth by making a tomographic renderisation with the software MIMICS. The numeric

4. Seismic Performance of Post-Northridge Welded Connections
Abstract Post-Northridge welded connections are widely used in engineering projects as lateral-force-resisting systems. In this study, we aim to assess the cyclic performance of the post-Northridge welded connections to compare the connections with each other. For this purpose, we focus on Welded Unreinforced Flange – Welded Web (WUF-W), Welded Flange Pla

5. Finite element simulation of fracture in a restored premolar tooth using high aspect ratio elements
Abstract Introduction The term cracked tooth syndrome refers to an incomplete fracture of a vital posterior tooth that involves the dentin and occasionally extends into the pulp. There is a very limited number of publications trying to model dentin crack growth using numerical techniques. Therefore, it is essential to numerically model this phenomenon in o

6. Finite Element Simulation of Welding Distortion in Dissimilar Joint by Inherent Deformation Method
Abstract Fusion welding is widely used to join different parts to each other in various industries. However, welding-induced distortions sometimes cause problems such as misalignment during assembling and impose costs for their removal. Thus, it is imperative to predict and mitigate these problems to improve weldment quality and also reduce fabrication cost

7. Finite Element Analysis of Structures with Extruded Aluminum Profiles Having Complex Cross Sections
Abstract Extruded aluminum profiles are widely used in building and automation structures due to their durability, lightweight, corrosion resistance, shorter fastening time and reusability. Proper design is crucial in maintaining the lifespan of these structures. It is therefore essential to determine the structural behaviors of the structures such as the na

8. Computational Modelling of RC Slabs Cracking with an Embedded Discontinuity Formulation
Abstract This paper investigates the cracking process of reinforced concrete slabs subjected to vertical load, involving their crack pattern and the load-displacement capacity curve. Concrete was discretized with hexahedral finite elements with embedded discontinuities; whereas steel reinforcement was represented by 3D bar elements, placed along the edges of

9. Analysis of the stresses in corrugated sheets under bending
This paper presents three different numerical models for the evaluation of the stresses in corrugated sheets under bending. Regarding the numerical simulations different approaches can be considered, i.e., a elastic linear analysis or a physical nonlinear analysis, that considers criteria to fail for the sheet material. Moreover, the construction of the fini

10. Blast resistance of stiffened sandwich panels with closed-cell aluminum foam
In the present investigation, response of the stiffened sandwich foam panels with closed-cell aluminum foam cores subjected to blast load is examined. The panels have the metal foam sandwiched between two steel sheets. To improve resistance of the sandwich foam panel against blast, stiffeners are provided and their dynamic response under varying blast load i

Sobre modelos constitutivos não lineares para materiais com gradação funcional exibindo grandes deformações: implementação numérica em formulação não linear geométrica / On nonlinear constitutive models for functionally graded materials exhibiting large strains: numerical implementation in geometrically nonlinear formulation
O objetivo precípuo deste estudo é a implementação computacional de modelos constitutivos elásticos e elastoplásticos para materiais com gradação funcional em regime de grandes deslocamentos e elevadas deformações. Para simular numericamente um problema estrutural, são empregados aqui elementos finitos sólidos (tetraédrico e hexaédrico) com ord

12. Uma estratégia numérica para análise termoelástica de sólidos recobertos com filmes de material funcionalmente gradado (FGM) / A strategy for numerical thermoelastic analysis of solid film coated with functionally grated material (FGM)
O método de elementos finitos tem sido tradicionalmente aplicado na solução de problemas de elasticidade e transferência de calor, sendo amplamente utilizado em casos com materiais homogêneos e isotrópicos. Com o advento de novas tecnologias tem sido mais freqüente a utilização de componentes com mais de um material, onde se procura obter o máximo
