This work uses refined first-order shear theory to analyze the free vibration and transient responses of double-curved sandwich two-layer shells made auxetic honeycomb core laminated three-phase polymer/GNP/fiber surface subjected blast load. Each two layers that make up shell structure is an sheets polymer/GNP/fiber. The exterior supported by a Kerr elastic foundation with three characteristics. key innovation proposed transverse stresses are zero at surfaces each layer. In contrast previous deformation theories, no correction factor required. Navier's exact solution was used treat problem single title boundary, while finite element technique eight-node quadrilateral were address other boundary requirements. To ensure accuracy these results, thorough comparison employed in conjunction credible statements. model's edge cases allow for this kind analysis. study's findings may be post-construction evaluation military civil works structures their ability sustain explosive loads. addition, also important basis calculation design smart materials when shock waves or

Nonlinear Forced Vibration Analysis of Two-Directional Functionally Graded Truncated Conical Shells

International Journal of Structural Stability and Dynamics, Journal Year: 2023, Volume and Issue: 24(12)

Published: Sept. 4, 2023

It is crucial to comprehend the nonlinear vibration behavior of sophisticated engineering constructions aid in examination, creation and production procedures. The primary objective this study, therefore, focus on exploring forced vibrational characteristics two-directional functionally graded (TDFG) cone-shaped shell for first time. To accomplish this, motion equations TDFG are derived based upon framework first-order shear deformation theory (FSDT) conjunction with von Kármán assumption. models have mechanical properties that can change smoothly continuously across thickness length shell, following a power law distribution pattern. discretize partial differential transform them into ordinary equations, Galerkin approach was used ultimately, these were solved using multiple time scales method. accuracy effectiveness analytical model indicated through comparison existing solutions. Finally, some comprehensive parametric investigations carried out gain insight impacts several factors highlighting significant influence transverse longitudinal gradient indices frequency response, which not considered before. new insights gained from research could serve as valuable benchmark outcomes well contribute more understanding vibrations future analysis design processes.
