Behavior of wall panels in industrial buildings caused by differential settlements
(Techno-Press, 2015-11)
This paper presents the analysis of mechanical behavior of metal wall panels of storehouses and industrial buildings subjected to differential settlements. The storehouses considered are representative of those used in the ...
Design of a wind turbine generator for rural applications
(Institution of Engineering and Technology, 2019-03)
This paper presents a wind-generation system design for rural applications. In Southern areas of Argentina, there are right conditions for wind energy exploitation. Depending on the characteristics of these areas, the ...
Fast analysis of cylindrical microstrip lines printed on substrates composed of multiple layers
(John Wiley and Sons Inc., 2010)
This letter presents an analysis of microstrip lines that are printed on substrates composed of numerous dielectric layers using a fast technique that comprises the full-wave equivalent circuit and the discrete mode matching ...
An augmented lagrangian method to solve three-dimensional nonlinear contact problems
(Planta Piloto de Ingeniería Química, 2012-11)
A finite element formulation to deal with the friction contact problem between an elastic body and a rigid foundation is presented. An augmented Lagrangian method, which incorporates two Lagrange multipliers and a slack ...
Optimal a priori error estimates in weighted Sobolev spaces for the Poisson problem with singular sources
(EDP Sciences, 2021-08)
We study the problem -Δu=f, where f has a point-singularity. In particular, we are interested in f = δx0, a Dirac delta with support in x0, but singularities of the form f|x - x0|-s are also considered. We prove the stability ...
Improved First Order Formulation for Buckling Analysis of Functionally Graded Beams
(Institute of Electrical and Electronics Engineers Inc., 2020-09-30)
In this research, an improved first order formulation is presented to study the critical buckling load in functionally graded beams. The formulation has five independent variables in comparison with the Timoshenko theory ...
Cohesive surface model for fracture based on a two-scale formulation: computational implementation aspects
(Springer, 2016-10)
The paper describes the computational aspects and numerical implementation of a two-scale cohesive surface methodology developed for analyzing fracture in heterogeneous materials with complex micro-structures. This approach ...
The Steklov eigenvalue problem in a cuspidal domain
(Springer, 2020-02)
In this paper we analyze the approximation, by piecewise linear finite elements, of a Steklov eigenvalue problem in a plane domain with an external cusp. This problem is not covered by the literature and its analysis ...
