“…Substituting the expressions for U, W, and T from Equations (32,36) and (37) into Equation (31) and integrating by parts, and collecting the coefficients of u 0 , w 0 , c , t and b , the following equations of motion for the sandwich beam with soft core are obtained…”

“…Therefore, this numerical example well validates the high accuracy of the present model in static analysis of symmetric sandwich beams. For the second numerical example, an asymmetric sandwich beam, which was previously studied in the literature, 32 is considered. The beam is simply supported at both ends and subjected to a transverse sinusoidal distributed load q(x) = q 0 sin( x/L) applied on the top surface.…”

“…These lower order two-and threenoded elements were then extended to an entire class of higher-order elements by Di Sciuva et al [37]. The same interpolation scheme was also used in a version of RZT (m) with cubic in-plane displacement field and quadratic transverse displacement [38].…”
