1. Physical and geometric non-linear analysis using the finite difference method for one-dimensional consolidation problem
Abstract This article presents a numerical model based on the finite difference method for the physical and geometric non-linear analysis of a one-dimensional consolidation problem regarding a saturated, homogeneous and isotropic soil layer with low permeability and high compressibility. The problem is formulated by adopting the void ratio as the primary var

4. Shear Strengthening of RC Deep Beams with Sprayed Fiber-reinforced Polymer Composites (SFRP): Part 2 Finite Element Analysis
AbstractThis paper presents the finite element analysis conducted on SFRP strengthened reinforced concrete (RC) deep beams. The analysis variables included SFRP material (glass and carbon), SFRP thickness (3 mm and 5 mm), SFRP configuration and strength of concrete. The externally applied SFRP technique is significantly effective to enhance the ultimate load

5. Physical and geometrical non-linear analysis of plane frames considering elastoplastic semi-rigid connections by the positional FEM
This study presents an alternative Finite Element formulation based on positions to model plane frames considering geometrical non-linear and elastoplastic behavior for members and semi-rigid connections. The formulation includes shear effects and allows the consideration of important mechanical behavior of structures in design decisions and verifications. T

6. Magnetohydrodynamic axisymmetric flow of a third-grade fluid between two porous disks
This paper investigates magnetohydrodynamic axisymmetric flow of a third-grade fluid between two porous disks. The governing partial differential equations are transformed into ordinary differential equations by similarity transformations. The resulting non-linear problem is solved by a homotopy analysis method (HAM). The effects of dimensionless parameters

9. Regionalização de vazões médias de longo período e de volumes de reservatórios de regularização
In this work, hydrological regionalization was utilized for estimating long-period average flow and reservoirs volumes in watersheds. For the regionalization of longperiod average flows, were analyzed three methods: Eletrobrás (1985a), linear interpolation, and Chaves et al. (2002). The acquisition of physical and climatic information, for regionalization,
