1. Study About Buckling Phenomenon in Perforated Thin Steel Plates Employing Computational Modeling and Constructal Design Method
Abstract Perforated steel thin plates are commonly used in structural engineering. Due to their geometric characteristics, these panels can suffer the undesired buckling phenomenon. In this context, the present work associates the computational modeling and the constructal design method to evaluate the influence of the geometric configuration in the plate bu

2. Determination of the rheological properties of thin plate under transient vibration
The article deals with systematic analysis of the transient vibration of rectangular viscoelastic orthotropic thin 2D plate. The analysis is focused on specific deformation models of plate and for specific linear models of rheological properties. The viscoelastic isotropic and anisotropic (orthotropic) materials were investigated. The plate is loaded by gene

6. Multidimensional modelling and calculation of combustion in porous media
In contrast with household heating systems based on open combustion flames, burners based on premixed combustion in inert porous media are characterized by higher thermal efficiency and high turndown ratio allied with compacity of the units. Moreover, porous burners, where a flame is anchored inside a porous matrix, are associated with low pollutants formati

10. A three layer quasi 3D finite element model for structural analysis of sandwich plates.
A three-layer finite element model for the analysis of sandwich plates with laminated composite face-sheets is evaluated. In the model, the face-sheets are represented as Reissner-Mindlin plates and the core is modeled as a three-dimensional continuum. This representation allows accurate modeling for a wide range of core types. The three-dimensional problem

11. Ajuste de modelos numericos usando funções de resposta em frequencia
This work analyses numerical models updating techniques using simulated frequency response functions (FRFs) as experimental data. The usual techniques of finite element models (FEM) updating, those based on direct updating of model matrices, and those based on iterative methods are presented. The use of the iterative methods was investigated initially for FE
