Thermo-elastoviscoplastic snapthrough behavior of cylindrical panels

Computers & Structures, 1992
Summary: The thermo-elastoviscoplastic snapthrough behavior of simply supported cylindrical panels is investigated. The analysis is based on nonlinear kinematic relations and nonlinear rate-dependent unified constitutive equations which include both Bodner-Partom's and Walker's material models.

The Dynamic Response of Cylindrical and Conical Panels

Journal of Applied Mechanics, 1969
The dynamic response of cylindrical and conical panels subjected to arbitrary time-varying load distributions is studied and appropriate equations are presented. Convenient trigonometric series are used, in conjunction with finite-difference methods, to reduce the governing equations to sets of matrix equations.

Buckling Behavior of Pressure Loaded Cylindrical Panels

Journal of Engineering Mechanics, 1989
Buckling of pressure loaded cylindrical panels is investigated using a fully nonlinear Ritz solution procedure and a classical bifurcation analysis of an idealized model. The dialectic between these two contrasting approaches is shown to produce greater understanding than if either one of them were to be used alone. Apart from illuminating the specific

Imperfection sensitivity of cylindrically curved steel panels

Thin-Walled Structures, 2015
Abstract Unstiffened cylindrically curved panels constitute a common subset of shell structures and therefore share the advantages and disadvantages of such structural solution. One of the bigger disadvantages of shells is their sensitivity to imperfections that lower significantly their ultimate strength.

Nonlinear vibrations of circular cylindrical panels

Journal of Sound and Vibration, 2005
Abstract Large-amplitude (geometrically nonlinear) vibrations of circular cylindrical panels with rectangular base, simply supported at the four edges and subjected to radial harmonic excitation in the spectral neighbourhood of the lowest resonances are investigated.

Weight Optimization of Stiffened Cylindrical Panels

Journal of Pressure Vessel Technology, 1987
Many structures have curved panels with longitudinal, transverse, or orthogonal tee-stiffeners subjected to differential pressure, band loading, and axial and circumferential in-plane forces. Equations using energy methods are developed for the purpose of designing such cylindrical structures for minimum weight.

Response of orthogonally stiffened cylindrical shell panels

AIAA Journal, 1990
S shells find extensive use in the aircraft industry. The static analysis of cantilevered stiffened cylindrical shells subjected to internal pressure has been completed by Venkatesh and Rao, using doubly curved anisotropic shell elements. The free vibration of stiffened cylindrical shells has been investigated experimentally by Hoppman and analytically

Buckling of laminated composite cylindrical skew panels

Journal of Thermoplastic Composite Materials, 2015
Experimental studies were made on isotropic cylindrical skew panels made of Aluminum 7075-T6 and laminated composite cylindrical skew panels under uniaxial compression. The experimental values of the critical buckling load ( Pcr) were determined using five different methods.

Dynamic Stability of Circular Cylindrical Sandwich Panels

Journal of the Engineering Mechanics Division, 1971
A theoretical study of the dynamic stability of simply supported sandwich plates and circular cylindrical sandwich panels with dissimilar face-sheets and orthotropic cores is presented. The uniformly distributed periodic edge loads consist of steady components and oscillating components which are impulsive or vary according to an arbitrary piecewise ...

Dynamic Analysis of Orthotropic Laminated Cylindrical Panels

Mechanics of Advanced Materials and Structures, 2005
The dynamic response of an axisymmetric cross-ply laminated panel subjected to axisymmetric loading based on three-dimensional elasticity equations are studied. The shell panel is simply supported at four sides and has finite length. The highly coupled partial differential equations are reduced to ordinary differential equations with variable ...
