Abstract
The application of the ABAQUS finite element package to the analysis of a troughed-core steel sandwich panel is described, and the results are compared with those of closed solutions and experimental testing. Panels of this kind, which promise good strength-to-weight and strength-to-stiffness ratios, are of interest as lightweight decking for offshore platforms. The panel had high bending and shear stiffness in the x-direction, i.e. the direction of the core troughs, and low bending and shear stiffnesses in the y-direction. It had a length-to-breadth ratio of 3 and a span-to-depth ratio of about 56, with a self-weight of 62 kg/m2. Subjected to a uniformly distributed z-direction load of 10 kN/m2 over its entire surface, it experienced an experimental central deflection of span/133 when simply supported across its y-direction edges only and of span/428 when simply supported along all four edges.
