[Faculty] Fwd: [CSRC-SDSU COLLOQUIUM]: Numerical and Experimental Investigation of Tapered Closures in Sandwich Composites

[Jose Castillo]

*DATE: * Friday, January 31st, 2014

*TITLE:  *Numerical and Experimental Investigation of Tapered Closures in
Sandwich Composites

*TIME:*  3:30 PM

*LOCATION: * GMCS 214

*SPEAKER: * Dr. Satchi Venkataraman. Department of Aerospace Engineering at
San Diego State University

Sandwich composites used in aerospace and marine structures due to their
high specific bending stiffness and high specific in-plane strengths need
to be ramped down to a solid laminate along the edges for mechanical
fastening (bolts, rivets). These tapered ramps in sandwich panels have
large stress localized stress concentrations that lead to initiation and
growth of delamination failures. This talk presents a recent combined
numerical and experimental study conducted to evaluate the use of
functionally graded materials cores in sandwich composites to mitigate such
failures. The talk will highlight some remaining challenges in numerical
modeling and prediction of fracture initiation and growth at tapered
closures, and present some directions chosen for future investigation.
