Abstract
A study using the hybrid-stress model is presented to assess various through-thickness element stress distributions to be used in conjunction with a high-order plate theory. The plane-strain example problem of a semi-infinite plate under transverse sinusoidal loading is chosen so that a computationally efficient comparison of the stress assumptions can be made using 2-D plane-strain elements. The displacement assumption for all elements allows for inplane and transverse displacements which are cubic and quadratic, respectively. On the basis of results obtained in this pilot study, recommendations are made for extensions to single- or multi-layer thick plate elements.
