·        FREE FOR EVERYONE

• Meet at 7:00pm in the conference room at La Quinta Inn for food and refreshments.
• Follow at 8:00pm with our feature presentation, Ian Nieves, University of California Irvine talking on “Assisting Development of Characterization methods through FEA Simulation” in meeting room at La Quinta Inn.

This talk will be focused on a novel percussion-based mechanical testing instrument that has been developed for the characterization of laminated composites and defects. This instrument, or Periostat, assesses structural and intrinsic damping to determine material composition and the dimensions of gross defects such as delaminations. The Periostat is also predicted to hold significant promise as a diagnostic tool for the development of biomedical materials, where damping and intricate morphology stimulate tissue regeneration. Dynamic Finite element analysis (FEA) was used to verify the ability of the Periostat to detect the presence of energy dissipation and cracks in laminated and glass materials, the latter of which served as surrogates for rigid biological materials such as bone and enamel.  Similar FEA-based methodologies offer promise for facilitating the development of a wide range of characterization and research tools and methods.
