Airborne ultrasounds for damaged cementitious characterization

Gosálbez Castillo, Jorge; CARRIÓN GARCÍA, ALICIA; Gallardo, C.; Vázquez, S.; Genovés, V.; Paya Bernabeu, Jorge Juan (Acoustical Society of America, 2019-09-06)

[EN] The scope of this paper is to demonstrate the capability of airborne non-contact ultrasound (ANC-US) to assess thermal damage on normalized Portland cement mortar specimens. For this purpose, contact ultrasound (C-US) ...
Computer modeling and experimentation in radiofrequiency-based minimally invasive therapies

Ewertowska, Elzbieta (Universitat Politècnica de València, 2020-01-07)

[ES] La ablación por radiofrecuencia (RF) se ha convertido en una técnica ablativa importante, ampliamente utilizada en el área de las terapias mínimamente invasivas de la medicina moderna. El avance en el campo de las ...
Effects of high temperatures in the physical, mechanical, and drilling features of Prada limestone.

Martínez Ibáñez, Víctor (Universitat Politècnica de València, 2023-06-18)

[ES] Esta investigación se centra en la caliza de Prada, una formación del Cretácico inferior ubicada en la zona sur pirenaica de Cataluña (España). Se tomaron muestras de roca de sondeos perforados durante la etapa de ...
Flipped Accumulative Non-Linear Single Impact Resonance Acoustic Spectroscopy (FANSIRAS): A novel feature extraction algorithm for global damage assessment

Carrión García, Alicia; Genovés, V.; Pérez, G.; Paya Bernabeu, Jorge Juan; Gosálbez Castillo, Jorge (Elsevier, 2018)

[EN] High amplitude non-linear acoustic methods have shown great potential for the identification of micro-damage in inhomogeneous materials such as concrete. Usually, these methods evaluate non-linearity parameters related ...
Micro and macro-structural effects of high temperatures in Prada limestone: Key factors for future fire-intervention protocols in Tres Ponts Tunnel (Spain)

Martínez Ibáñez, Víctor; Garrido De La Torre, Mª Elvira; Hidalgo Signes, Carlos; Tomás, Roberto (Elsevier, 2021-06-07)

[EN] Temperature and cooling methods strongly affect the stability of tunnels drilled in rock masses and so condition interventions for fire emergencies. Samples from two horizontal boreholes drilled in Prada limestone ...
Nonlinear Acoustic Spectroscopy and Frequency Sweep Ultrasonics: Case on Thermal Damage Assessment in Mortar

Genovés, V.; CARRIÓN GARCÍA, ALICIA; Escobar, D.; Gosálbez Castillo, Jorge; Monzó Balbuena, José Mª; Borrachero Rosado, María Victoria; Paya Bernabeu, Jorge Juan (Springer-Verlag, 2019-09)

[EN] An exhaustive study on thermal damage of Portland cement-based materials is addressed. Damage carried out at different temperatures on concrete between 40 and 525 degrees C were assessed by means of microstructural, ...
