“…For efficient computation, equivalent single layer (ESL) theories such as the classical laminate theory (CLT) (Kwak et al., 2009; Li et al., 2012; Li and Narita, 2013; Mahmoodi and Ahmadian, 2010; Ray, 2003; Song and Li, 2014), first-order shear deformation theory (FSDT) (Balamurugan and Narayanan, 2001a,b; Dong et al., 2013; Liu et al., 2016; Narayanan and Balamurugan, 2003; Raja et al., 2004), third-order theory (TOT) (Correia et al., 2002) and higher-order theory (HOT) (Kulkarni and Bajoria, 2003) have been mostly employed for obtaining the active vibration control of smart plate/shell structures. These theories are derived assuming a single polynomial function (of first, third or higher order) of the thickness coordinate for the displacement variables to be valid in all layers irrespective of their different material properties and thicknesses.…”
