Table 8 Effect of piezoelectric to Gori thickness ratio \(\:{\varvec{h}}_{\varvec{p}}/{\varvec{h}}_{\varvec{e}}\) on the changes of frequencies of the sandwich curved beam with changes of thermal loads.

From: A unified multifield formulation for analysis of a sandwich graphene origami reinforced composite curved structure

\(\:{T(}^{O}K)\)

\(h_{p} /h_{e} = 0.1\)

\(h_{p} /h_{e} = 0.09\)

\(h_{p} /h_{e} = 0.08\)

\(h_{p} /h_{e} = 0.05\)
