    • A predictive model for fracture in human ribs based on in-vitro acoustic emission data 

      García Vilana, Silvia; Sánchez Molina, David; Llumà Fuentes, Jordi; Fernández Osete, Ismael; Velázquez Ameijide, Juan; Martínez González, Eva (2021-09-01)
      Article
      Open Access
      Purpose The aim of this paper is to propose a fracture model for human ribs based on acoustic emission (AE) data. The accumulation of microcracking until a macroscopic crack is produced can be monitored by AE. The ...
    • Advanced analysis of in-service movements of vehicle closures 

      Fernández Osete, Ismael; Montané, Francesc Xavier; García, Juan Jesús; Maureso, Miquel (2004)
      Conference lecture
      Open Access
      Closures (doors, hood, tailgate, etc.) are attached to the vehicle body by means of articulated elements that allow a high level of mobility. This may cause the poor vibration performance of the closure when exposed to ...
    • Combination of acoustic emission and vibratory measure-ments to characterize an ultrasonic vibration assisted ball burnishing tool for a lathe 

      Fernández Osete, Ismael; Estévez Urra, Aida; Velázquez Corral, Eric; Valentín Ruiz, David; Llumà Fuentes, Jordi; Jerez Mesa, Ramón; Travieso Rodriguez, Jose Antonio (2021-07-14)
      Article
      Open Access
      In this paper, a resonant system that produces a movement of low amplitude and ultrasonic frequency is used to achieve the vibration assistance in a ball-burnishing process. A full vibration characterization of this process ...
    • Investigation of ball burnishing process using vibration and acoustic emission sensors 

      Fernández Osete, Ismael; Velázquez Corral, Eric; Marqués Salvador, Jordi-Adalbert; Llumà Fuentes, Jordi; Jerez Mesa, Ramón; Travieso Rodriguez, Jose Antonio (Institute of Physics (IOP), 2021-10-01)
      Article
      Open Access
      In this paper, a ball burnishing tool mounted in a CNC lathe is characterized. This tool may work as vibration assisted ball-burnishing tool and in conventional way. The characterization consists of acoustic emission ...
    • Ultrasonic vibration-assisted ball burnishing tool for a lathe characterized by acoustic emission and vibratory measurements 

      Fernández Osete, Ismael; Estévez Urra, Aida; Velázquez Corral, Eric; Valentín Ruiz, David; Llumà Fuentes, Jordi; Jerez Mesa, Ramón; Travieso Rodriguez, Jose Antonio (Multidisciplinary Digital Publishing Institute (MDPI), 2021-10-01)
      Article
      Open Access
      This paper focuses on a resonant system used to induce a low-amplitude movement and ultrasonic frequency to complement a ball burnishing process on a lathe. The system was characterized through the combination of different ...
