“…In recent years, substantial effort has been dedicated to understanding the vibrational characteristics of laminated composite structures in the presence of various environmental conditions. Several scholars have investigated the dynamic response of the composite structures such as beams [3,[12][13][14], shells [6,7,15,16], and plates [2,17,18] using various analytical, numerical, and experimental methods. Sobhy [12] proposed a new four-variable shear deformation theory to investigate the vibration and buckling behavior of functionally graded (FG) sandwich plates.…”
