• Troxler Electronic Laboratories - Intern

  2011 - 2011 The research project was about the design of a novel technique for testing mechanical properties of soil based materials, including the design of its associated apparatus.
  
  We built a FEM model of the system, which served as a support for numerical simulations using COMSOL. Conducted simulations combined with laboratory observations gave a clear insight of the mechanical behavior of the system, which led to the foundations for the design of a low frequency, multi-resolution testing instrument. The instrument along with its associated methodology showed a clear reading of the segregated wave’s velocity between, compression, shear and Rayleigh waves within the medium, providing a mean for back-calculating soil’s physical characteristics.
  
  The instrument was successfully tested during a field campaign conducted at the military site of the Army Corps of Engineers, New Orleans.
  
  Skills and techniques: Data acquisition systems (IAR for ARM7), Data mining and analysis (Matlab), Mechanical system design (CAO-Catia) and supervision of fabrication in house, IEPE accelerometers analog front end design and instrumentation electronic chain.
