      [Abstract]: Although the shipbuilding industry is constantly demanding new advanced joining solutions, adhesive technology is not as developed in the marine as compared to other industries. The main reason is the lack ...
    • Comparison by thermal analysis of Joule‑cured versus oven‑cured composites 

      Vázquez, Laura; López-Beceiro, Jorge; Díaz-Díaz, Ana-María; Álvarez García, Ana; Pereira Rodríguez, Mercedes; Artiaga, Ramón (Springer, 2024-03-20)
      [Abstract]: The current technology for curing high-performance composites, such as those used in industries like such as aeronautics and the automotive industry, is based on the use of autoclaves, where the material is ...
    • Ejes del Desarrollo del Espacio Iberoamericano del Conocimiento. Análisis comparativo con el Espacio Europeo de Educación Superior 

      Álvarez García, Begoña; Boedo, Lucía; Álvarez García, Ana (Organización de Estados Iberoamericanos para la Educación, la Ciencia y la Cultura (OEI), 2011)
      [Resumen]: El Espacio Iberoamericano del Conocimiento (eic) ha pasado de ser un ambicioso proyecto a convertirse en una realidad que refleja el enorme interés que tienen los países iberoamericanos por mejorar sus sistemas ...
    • Ensayos experimentales para la obtención del coeficiente hidráulico como un factor relevante en el desarrollo del proyecto de un buque 

      Álvarez García, Ana; Rodríguez-García, JuanDeDios; González López, Primitivo B. (2010-11-15)
      [Resumen]En este artículo se presenta un estudio experimental del comportamiento de un modelo sujeto a la inundación progresiva de sus compartimentos. El estudio consta de varios ensayos mediante los que se inunda uno o ...
    • Kinetics of Thermal Degradation of Cellulose: Analysis Based on Isothermal and Linear Heating Data 

      López-Beceiro, Jorge; Álvarez García, Ana; Sebio-Puñal, Sebio; Zaragoza, Sonia; Álvarez García, Begoña; Díaz-Díaz, Ana-María; Janeiro Arocas, Julia María; Artiaga, Ramón (NC State University, 2016-05-16)
      [Abstarct]: In spite of the many studies performed, there is not yet a kinetic model to predict the thermal degradation of cellulose in isothermal and non-isothermal conditions for the full extent of conversion. A model ...

    • Predicting lifetime of adhesive bonds for naval steel by time-temperature superposition 

      Rodríguez-Dopico, Francisco J.; Álvarez García, Ana; Tarrío-Saavedra, Javier; Meneses Freire, Antonio; Naya, Salvador (Elsevier, 2024-12-01)
      [Abstract] There is a lack of knowledge about the long-term behaviour of adhesive joints in the marine environment, and for hence, its reliability. The life cycle expected for a ship is twenty-five years and conduct duration ...
    • Temperature Simulation of Three-Point Bending Geometry in a Dynamic Mechanical Analyzer 

      Gracia-Fernández, Carlos; Álvarez García, Ana; Gómez Barreiro, Silvia; López-Beceiro, Jorge; Artiaga, Ramón (Elsevier, 2021-01)
