An Effective 2D Linear Elasticity Vibrational Model for Layered and Sandwich Clamped-Clamped Unidirectional Strips

A New 2D Local Vibrational Model for Unidirectional Clamped—Clamped Sandwich Structure with Edge Stiffeners

“…However, the lines SKs-Exp, VSS-Exp were proposed as smooth elongations of the curves SKs-ExExp and VSS-ExExp, respectively. Thus, the lines SKs-Exp and VSS-Exp correspond to probable experimental results and they suggest that the experimental eigenfrequencies for m ¼ 1(s) and m ¼ 2(a) are much higher than the corresponding computational eigenfrequencies predicted by the models proposed in Sokolinsky and Nutt [13] and Karczmarzyk [15].…”

“…It is seen in Figure 1 that the results predicted by the models [10,13,15] are close, the curves RAV-SKs and VSS-SKs are parallel, and distant approximately 6%. Model [11] gives lower eigenfrequencies than the models [10,13,15]. However, comparisons of the computational results 8.00% 6.00% 4.00% 2.00% 0.00% −2.00% −4.00% −6.00% −8.00% −10.00% −12.00% −14.00% −16.00% −18.00%…”

“…The model presented in Sokolinsky and Nutt [13] is a particular case of the plate model I proposed in Frostig and Thomsen [4]. Let us look at the percentage differences between eigenfrequencies obtained experimentally [10] and the counterparts predicted by the analytical models [11,13,15] (Figure 1).…”

“…Here a few of them are collected [10][11][12][13][14][15]. It is noticed that the experimental data given in Raville et al [10] are compared in Sakiyama et al [11], Sokolinsky and Nutt [13], Howson and Zare [14], and Karczmarzyk [15]. The model presented in Sokolinsky and Nutt [13] is a particular case of the plate model I proposed in Frostig and Thomsen [4].…”

“…VSS , ! SKs , appearing in the abbreviations, stand for computational eigenfrequencies predicted by the analytical models presented in Raville et al [10], Sakiyama et al [11], Sokolinsky and Nutt [13], Karczmarzyk [15], respectively. The symbol !…”
