“…In the two-dimensional case the problem is related to a class of Kirchhoff-Boussinesq models studied by Chueshov and Lasiecka [5,6,9]. In general, problem (1.1) models vibrations of elastic plates with nonlinear shear strain, as considered by Esquivel-Avila [12], Liu and Xu [26,27], Wang and Wang [32], Yang [36][37][38] and Yang and Jin [39]. In addition, a viscoelastic version of the problem with a memory term was proposed by Andrade, Jorge Silva and Ma [2,22,23].…”
