Vibration Analysis of a Sandwich Plate with Laminated Face and Porous Core Layers Resting on Elastic Foundation

Dispersion of an inhomogeneous sandwich plate having imperfect interfaces and supported by the Pasternak foundation

“…In other words, the shear moduli parameters χ j and the Winkler parameters κ j , where j = 1, 2, of the Pasternak foundation have the same trend; however, in the case of a sandwich plate with stiff skin layers and a soft core layer, the effects of the Winkler parameters are significantly larger than the shear moduli parameters. This fact was also seen in the case of a sandwich plate with a laminated face and porous core layers supported over the Pasternak foundation and reported by Yüksel and Akbas [37].…”

“…Vibrational analysis of elastic structures supported on foundations requires knowledge of both structural and foundation parameters, and further investigations of structures interacting with elastic foundations are frequently carried out by modeling foundation. Various innovative foundation models like Winkler foundation [28][29][30][31][32][33][34], Visco-elastic foundation [31,35], two-parameter Winkler-Pasternak foundation [36][37][38][39][40][41][42] and Visco-Pasternak foundation [43][44][45] have been used to analyze the dynamic and static excitation of beams, plates, and multilayered structures. Younesian et al [44] and Wang et al [45] offered a comprehensive overview of elastic structures on different foundation models, which included everything from the most basic foundation models to the most complex, as well as the most recent theories on the subject.…”

“…Numerous multilayered structures are built utilizing various material combinations based on industrial use or demand and are then interacted with innovative and hybrid foundations to examine the foundationstructure interaction. A detailed discussion of the interaction of structures with the Pasternak foundation may be found in [36][37][38][39][40][41][42][43] and references therein. Exclusively, the dispersion response of three-layered plates with different material properties and layers configuration, interacting with the Pasternak foundation, subject to porosity in the core layer and hygrothermal effects have been discussed in [37,38], respectively.…”

Furthermore, as scientists and industries have become more interested in composite material mechanics, research concerning interfaces among deformable materials increased considerably.…”

Buckling Analysis of Porous Orthotropic Laminated Plates Within Higher-Order Shear Deformation Theory

“…Tabakalı kompozit malzemelerin üretimi esnasında meydana gelen mikro-kusurların da incelenmesi ve tabakalı kompozit plakların statik ve dinamik davranışları üzerindeki etkilerinin belirlenmesi gerekmektedir. Bu ihtiyaçtan ötürü son yıllarda poroz tabakalı yapı elemanlarının eğilme problemlerinin çözümüne eğilim artmıştır [31][32][33].…”
