Application of PHT-splines in bending and vibration analysis of cracked Kirchhoff-Love plates
(Elsevier, 2020)
In this work, we present an eXtended Geometry Independent Field approximaTion (X-GIFT) formulation for cracked Kirchhoff-Love plates. The plate geometry is modeled by Non-Uniform Rational B-Splines (NURBS) while the solution ...
h- and p-adaptivity driven by recovery and residual-based error estimators for PHT-splines applied to time-harmonic acoustics
(Elsevier Ltd, 2019)
© 2019 Elsevier Ltd In this work, we demonstrate the application of PHT-splines for time-harmonic acoustic problems, modeled by the Helmholtz equation. Solutions of the Helmholtz equation have two features: global oscillations ...
Análise de técnicas de refino H-adaptativo em MEF utilizando estimativas de erro a posteriori em problemas de elasticidade unidimensional
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia MecânicaUTFPR, 2018-07-02)
Finding the exact solution for boundary value problems, in physical systems modeling for engineering purposes, can be complex or even imposible. Then, the Finite Element Method (FEM) is an available alternative to obtain ...
Automatic Recovery Estimation of Degraded Soils by Artificial Neural Networks in Function of Chemical and Physical Attributes in Brazilian Savannah Soil
(Taylor & Francis Inc, 2019-06-27)
The Oxisols is predominant in 54% of Brazilian territories and characterized by high weathering, relatively low chemical properties, and adequate structure. This study aimed to analyze the Oxisols through an Artificial ...
Estimadores de erro a posteriori para o Método dos Elementos Finitos Generalizados (MEFG) aplicados à análise de estruturas de concreto
(Universidade Federal de Minas GeraisUFMG, 2016-05-20)
This work provides a brief description of the main potentialities of the Generalized Finite Element Method (GFEM), which make it a robust tool for solving a wide range of numerical problems. Next, it is introduced the ...
Análisis de las incertidumbres para la mejora de la confiabilidad en la contabilidad metalúrgica basado en la teoría de muestreo
(Universidad Nacional de IngenieríaPE, 2022)
Small perturbations in a finger-tapping task reveal inherent nonlinearities of the underlying error correction mechanism
(Elsevier Science Bv, 2013-02)
Time estimation is critical for survival and control of a variety of behaviors, both in humans and other animals. Time processing in the few hundred milliseconds range, known as millisecond timing, is involved in motor ...
