Micromechanical approach for the analysis of wave propagation in particulate composites
Cristhian Fernando Rojas-Cristancho, Florence Dinzart, Octavio Andrés González Estrada
Laser ultrasonic non-destructive testing is widely used for the inspection of mechanical structures. This method uses the propagation of ultrasonic guided waves (UGW) in the media.…
Damage detection in a unidimensional truss using the firefly optimization algorithm and finite elements
Camilo Manrique Escobar, Octavio Andrés González-Estrada, Heller Guillermo Sánchez Acevedo
In this paper, we investigate the damage detection of structures seen as an optimization problem, using modal characterization to evaluate the dynamic response of the structure giv…
Report: Error estimation of recovered solution in FE analysis
Enrique Nadal Soriano, Octavio Andrés González Estrada, Juan José Ródenas García +1
The recovery type error estimators introduced by Zienkiewicz and Zhu use a recovered stress field evaluated from the Finite Element (FE) solution. Their accuracy depends on the qua…
NURBS-based finite element analysis of functionally graded plates: static bending, vibration, buckling and flutter
Navid Valizadeh, Sundararajan Natarajan, Octavio A Gonzalez-Estrada +3
In this paper, a non-uniform rational B-spline based iso-geometric finite element method is used to study the static and dynamic characteristics of functionally graded material (FG…
Mesh adaptivity driven by goal-oriented locally equilibrated superconvergent patch recovery
Octavio Andrés González Estrada, E. Nadal, J. J. Ródenas +3
During the last decade there has been an increase on the use of goal-oriented error estimates which help to quantify and control the local error on a quantity of interest (QoI) tha…
Enhanced error estimator based on a nearly equilibrated moving least squares recovery technique for FEM and XFEM
J. J. Ródenas, Octavio Andrés González Estrada, F. J. Fuenmayor +1
In this paper a new technique aimed to obtain accurate estimates of the error in energy norm using a moving least squares (MLS) recovery-based procedure is presented. We explore th…
