Meruane Naranjo, Viviana; Aichele Figueroa, Diego; Ruiz García, Rafael; López Droguett, Enrique (Hindawi, 2021)The vibrational behavior of composite structures has been demonstrated as a useful feature for identifying debonding damage. The precision of the damage localization can be greatly improved by the addition of more measuring ...

Meruane Naranjo, Viviana; Heylen, W. (ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011-07)An hybrid real-coded Genetic Algorithm with damage penalization is implemented to locate and quantify structural damage. Genetic Algorithms provide a powerful tool to solved optimization problems. With an appropriate ...

San Martin, Gabriel; López Droguett, Enrique; Meruane Naranjo, Viviana; das Chagas Moura, Márcio (SAGE Publications Ltd, 2019)© The Author(s) 2018.One of the main challenges that the industry faces when dealing with massive data for failure diagnosis is high dimensionality of such data. This can be tackled by dimensionality reduction method such ...

Meruane Naranjo, Viviana; Véliz, Pablo; López Droguett, Enrique; Ortiz Bernardín, Alejandro (MDPI, 2017)To avoid structural failures it is of critical importance to detect, locate and quantify impact damage as soon as it occurs. This can be achieved by impact identification methodologies, which continuously monitor the ...

Meruane Naranjo, Viviana; Del Fierro, Valentina; Ortiz Bernardín, Alejandro (Entropy, 2014)Honeycomb sandwich structures are used in a wide variety of applications. Nevertheless, due to manufacturing defects or impact loads, these structures can be subject to imperfect bonding or debonding between the skin and ...
-
Meruane Naranjo, Viviana (Elsevier, 2013)Traditional model updating methods make use of modal information as natural frequencies and mode shapes. Natural frequencies can be accurately identified, but this is not the case for mode shapes. Mode shapes are usually ...
-
Real-Time Structural Damage Assessment Using Artificial Neural Networks and Antiresonant Frequencies Meruane Naranjo, Viviana; Mahu Sinclair, Javier Antonio (Hindawi, 2014)The main problem in damage assessment is the determination of how to ascertain the presence, location, and severity of structural damage given the structure’s dynamic characteristics. The most successful applications of ...

Ruiz García, Rafael; Meruane Naranjo, Viviana (Institute of Physics, 2017)The goal of this work is to describe a framework to propagate uncertainties in piezoelectricenergy harvesters(PEHs). These uncertainties are related to the incomplete knowledge of themodel parameters. The framework presented ...
