Paper Abstract
The multifunctional hybrid composite structure studied here consists of a ceramic outer layer capable of
withstanding high temperatures, a functionally graded ceramic layer combining shape memory alloy (SMA)
properties of NiTi together with Ti2AlC (called Graded Ceramic/Metal Composite, or GCMeC), and a high
temperature sensor patch, followed by a polymer matrix composite laced with vascular cooling channels all held
together with various epoxies. Due to the recoverable nature of SMA and adhesive properties of Ti2AlC, the
damping behavior of the GCMeC is largely viscoelastic. This paper presents a finite element formulation for this
multifunctional hybrid structure with embedded viscoelastic material. In order to implement the viscoelastic model
into the finite element formulation, a second order three parameter Golla-Hughes-McTavish (GHM) method is used
to describe the viscoelastic behavior. Considering the parameter identification, a strategy to estimate the fractional
order of the time derivative and the relaxation time is outlined. The curve-fitting aspects of both GHM and ADF
show good agreement with experimental data obtained from dynamic mechanics analysis. The performance of the
finite element of the layered multifunctional beam is verified through experimental model analysis.
