Finite shell elements for geometrically and materially nonlinear stress and stability analyses of layered fibre reinforced composite shells as well as sandwich shells with orthotropic core material are presented. The element formulations are based on the degeneration principle including large displacements with an efficient analytical thickness ...

Higher-order Closed-form Solutions for Free Vibration of Laminated Composite and Sandwich Shells
Journal of Sandwich Structures and Materials, 2006 Closed-form formulations of 2-D higher-order shear deformation theories (HOSTs) for the free vibration analysis of simply supported cross-ply laminated composite and sandwich doubly curved shells are presented. The formulation includes the Sanders theory

Modal response of all-composite corrugated sandwich cylindrical shells
Composites Science and Technology, 2015Abstract A series of all-composite axial and circular corrugated sandwich cylindrical shells is manufactured using a novel hot press moulding method. Modal testing is conducted to investigate vibration characteristics of such composite corrugated sandwich cylindrical shells with free–free boundary condition.

Analysis and Testing of a Composite Sandwich Shell Horizontal Tail
1992This paper presents the preliminary results of an investigation into the use of a sandwich shell without spars or ribs as a horizontal tail on a light general aviation aircraft. The primary motivations for designing such a structure are simplicity, ease of construction, and the reduction of fasteners. The structure investigated consisted

Optimal Design of Composite Shelled Sandwich Structures with a Honeycomb Filler
2021The multi-parameter problem of the optimal design of composite sandwich structures with the honeycomb filler has been solved. For this purpose, the optimization process was divided into several stages according to the reasonable levels of significance of the objective function’s parameters, i.e., minimal weight. At the first stage, preliminary analysis

Dynamics properties of composite sandwich open circular cylindrical shells
Composite Structures, 2018Abstract This paper deals with the dynamic properties of three-layered composite sandwich open circular cylindrical shells (CSOCCS). First, the equations of motion that govern the free vibrations of CSOCCS are derived by applying Hamilton’s principle based on the first-order shear deformation shell theory.

Free Vibration Analysis of Composite Sandwich Shells Using Higher Order Shell Elements
46th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics and Materials Conference, 2005A family of assumed strain shell elements based on a refined higher order theory is used to analyze the natural frequencies of composite sandwich shells. The higher order theory contains in-plane displacements that are expanded to include the higher order terms in the Taylor series expansion as a result of which there is no need for shear correction ...

58th AIAA/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2017
The paper presents a probabilistic methodology for the buckling analysis of sandwich composite cylindrical shells. The sensitivity to experimentally-measured imperfections is probabilistically assessed in terms of a loading factor, named probabilistic buckling factor.

Free vibration response of composite sandwich cylindrical shell with flexible core
Composite Structures, 2010This study deals with the free vibration analysis of composite sandwich cylindrical shell with a flexible core using a higher order sandwich panel theory. The formulation uses the classical shell theory for the face sheets and an elasticity theory for the core and includes derivation of the governing equations along with the appropriate boundary ...
