“…where G 0 represents the relaxed magnitude of the shear modulus, τ β r represents the time needed for relaxation and G ∞ represents the material modulus after being relaxed for long-terms. Assuming a harmonic solution [49] for the vibrations of a three-layer cylindrical shell, the stress-strain relationships for the core layer can be considered as follows:…”

“…For parametric analysis, a soft-core having three different thickness values is added. Soft-core material parameters have been taken from the study (Taskin et al, 2019) and are shown in Table 5. composite plies with a thickness of h= 0.63 mm, in the middle foam core material with a thickness of 5h= 3.15 mm, and on the back face 2 composite plies with a thickness of h= 0.63 mm are used, forming a 4.41 mm thickness value in total, as can be seen in Figure 8.…”
