1. Calibration of simulation parameters for wind erosion gas-solid two-phase flow in arid and semiarid soils
RESUMO Para construir um modelo de simulação acoplada da erosão eólica do solo e fluxo bifásico em regiões áridas e semi-áridas, os parâmetros de contato apropriados do modelo de simulação de elementos discretos do solo são obtidos com base no teste de calibração do ângulo de repouso (AoR). O modelo de simulação acoplado foi estabelecido atr

2. Nonlinear numerical analysis of composite slabs with steel decking
Resumo O comportamento das lajes mistas é governado pelo cisalhamento longitudinal na interface entre o aço e o concreto, que é desenvolvido em lajes sob flexão simples. O método m-k e o método da interação parcial, utilizados no cálculo da resistência ao cisalhamento na interface aço-concreto de lajes mistas, são baseados em ensaios experimentai

3. Large deflection and initial instability analysis of anisotropic plates by the generalized finite element method
Abstract This paper presents investigations laminated plates under moderately large transverse displacements and initial instability, through the Generalized Finite Element Methods - GFEM. The von Kármán plate hypothesis are used along with Kirchhoff and Reissner-Mindlin kinematic plate bending models to approximate transverse displacements and critical bu

4. Single variable new first-order shear deformation theory for isotropic plates
Abstract This paper presents a single variable new first-order shear deformation plate theory with only one fourth-order partial governing differential equation. It may be noted that, first-order shear deformation plate theory of Mindlin has three coupled partial governing differential equations involving three unknown functions. Even a recently developed ne

6. A New Triangular Hybrid Displacement Function Element for Static and Free Vibration Analyses of Mindlin-Reissner Plate
Abstract A new 3-node triangular hybrid displacement function Mindlin-Reissner plate element is developed. Firstly, the modified variational functional of complementary energy for Mindlin-Reissner plate, which is eventually expressed by a so-called displacement function F, is proposed. Secondly, the locking-free formulae of Timoshenko’s beam theory are cho

7. Aula Magna de Pedro Arara Karo. Arara Karo: a persistência de um povo
resumo O líder Pedro Arara Karo, de Rondônia, faz um depoimento sobre a sua expulsão da terra indígena nos anos 1960, junto com a mãe e os irmãos, por seringalistas que os ameaçavam de morte. Os invasores empregavam os índios em regime semiescravo de barracão. Pedro cresceu como trabalhador em seringais sem saber que era índio e voltou adulto ao se

8. Time-Domain Three Dimensional BE-FE Method for Transient Response of Floating Structures Under Unsteady Loads
Abstract This paper presents a direct time-domain three dimensional (3D) numerical procedure to simulate the transient response of very large floating structures (VLFS) subjected to unsteady external loads as well as moving mass. The proposed procedure employs the Boundary Element and Finite Element methods (FEM-BEM). The floating structure and the surroundi

9. Size-Dependent Bending, Buckling and Free Vibration Analyses of Microscale Functionally Graded Mindlin Plates Based on the Strain Gradient Elasticity Theory
Abstract In this paper, a size-dependent microscale plate model is developed to describe the bending, buckling and free vibration behaviors of microplates made of functionally graded materials (FGMs). The size effects are captured based on the modified strain gradient theory (MSGT), and the formulation of the paper is on the basis of Mindlin plate theory. Th

10. Finite element model based on refined plate theories for laminated glass units
AbstractLaminated glass units exhibit complex response as a result of different mechanical behavior and properties of glass and polymer foil. We aim to develop a finite element model for elastic laminated glass plates based on the refined plate theory by Mau. For a geometrically nonlinear description of the behavior of units, each layer behaves according to

11. On the use of finite strip method for buckling analysis of moderately thick plate by refined plate theory and using new types of functions
AbstractA numerical method is developed for the buckling analysis of moderately thick plate with different boundary conditions. The procedure use the finite strip method in conjunction with the refined plate theory (RPT). Various refined shear displacement models are employed and compared with each other. These models account for parabolic, hyperbolic, expon
