Non linear fracture mechanics of polymers: Load Separation and Normalization methods
(Pergamon-Elsevier Science Ltd, 2012-01)
Fracture toughness of ductile polymers can be measured by the incremental crack growth resistance curve, where J-Integral value is plotted as a function of crack extension. The determination of the resistance curve, J-R, ...
Further results in J and CTOD estimation procedures for SE(T) fracture specimens - Part I: Homogeneous materials
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
This study provides further developments of the evaluation procedure for J and CTOD in SE(T) fracture specimens based on plastic eta-factors and load separation analysis. Non-linear finite element analyses for plane-strain ...

Load-separation method, Spb, used to estimate crack extension for J-R curves, modified for geometric variations in blunt-notched remaining ligament
(American Society Testing Materials, 2017-07)
The Spb method estimates stable crack growth in fracture mechanics precracked specimens test. It compares the load ratio between a precracked specimen that exhibits stable crack growth and a blunt-notched specimen with ...
Analysis of the Spb method for geometries where ηpl depends on a/W
(Elsevier, 2021-01)
Since its proposal, the simplified Spb method has been successfully applied to the fracture toughness evaluation of metallic and polymer materials. However, some points of this methodology remain unclear, like the applicability ...
Electric load forecasting using a fuzzy ART&ARTMAP neural network
(Elsevier B.V., 2005-01-01)
This work presents a neural network based on the ART architecture ( adaptive resonance theory), named fuzzy ART& ARTMAP neural network, applied to the electric load-forecasting problem. The neural networks based on the ...
