Non-linear analysis of sandwich plates

International Journal of Non-Linear Mechanics, 1987
The nonlinear static analysis of a sandwich plate using a quadratic isoparametric element having five degrees of freedom at each node is reported in this paper. The formulation includes the effects of large deformations and rotations besides stretching, bending and transverse shear.

Analysis and design of sandwich plates with inserts—a high-order sandwich plate theory approach

Composites Part B: Engineering, 1998
Abstract Sandwich structures are very susceptible to failure due to local stress concentrations induced in areas of load introduction, supports, geometrical and material discontinuities. These local stress concentrations are caused by localised bending effects, where the individual face sheets tend to bend about their own middle surface rather than ...

Optimization for buckling of composite sandwich plates

AIAA Journal, 1997
Summary: Consider a composite sandwich plate with balanced or unbalanced anisotropic composite laminated faces and an ideally orthotropic core. A closed-form solution of the buckling load is derived for the composite sandwich plates consisting of cross-ply symmetric laminate faces with all edges simply supported.

Enhancement of Blast Resistance of Sandwich Plates

Composites Part B: Engineering, 2005
This research examines the effect of design modifications on response of sandwich plates to impulse pressure loads. The objective is to limit damage by delamination of the laminated face sheets and by crushing of the structural foam core that dominates response of conventionally designed sandwich plates.

Delamination of a high-temperature sandwich plate

Experimental Mechanics, 2002
This paper describes the development of a method for determining the fracture toughness of the core/faceplate bond in high-temperature sandwich plates. The tensile deformation behavior of a sandwich element was also determined. The results from the latter experiment were used in a beam on elastic foundation analysis of the fracture specimen.

The Optimum Problem of the Sandwich Plate

Journal of Applied Mechanics, 1952
Abstract While numerous papers have been published on the stability of sandwich plates in compression, Fig. 1, so far, attention has almost exclusively been focused on the problem of finding the critical load under which the plate becomes unstable, assuming that the dimensions and the materials are given.

On the Torsion of Rectangular Sandwich Plates

Journal of Applied Mechanics, 1956
Abstract The torsional rigidity of rectangular sandwich plates of constant thickness is calculated, with cross sections assumed free to warp. The faces are isotropic and of equal thickness while the core may be orthotropic, the axes of orthotropy coinciding with co-ordinate axes of the structure.

Nonsinusoidal Buckling Modes of Sandwich Plates

Journal of the Aeronautical Sciences, 1954
Both wrinkling and "quasi-Euler" buckling modes of sandwich plates have hitherto been taken as sinusoidal. In this report the possibility of nonsinusoidal modes is investigated. The core slab material considered is the special orthotropic one which does not resist deformation in its own plane, but only extension and shear­ ing perpendicular to its ...
