Simply supported Sandwich Plate example
(OP)
I'm looking for design example of a simply supported sandwich plate subject to a uniform load normal to the face plates.
I've looked in many textbooks like Jones, Whitney, Ishai, Tsai, and Vasillev. Many have derivations but no complete examples.
I appreciate any suggestions.

The document contains a complete example for each load case.

Also, the Forest Products Laboratory (FPL) did a huge amount of research on sandwich structures decades ago, and an awful lot of their reports are available as downloads.
Having said that, most of the necessary stuff is adequately covered in the Diab and Hexcel references already given.
It depends a bit on what you mean by a "complete example".
RE: Simply supported Sandwich Plate example
I'm interested in the development of the extensional and flexibility stiffness matrices for a sandwich composed of cross ply laminates and the subsequent analysis to determine the maximum allowable load applied normal to the face. This should involve a classical plate theory solution but the maximum load I understand will be controlled by the failure modes of the first ply failure in the lamina or a variety of failures for the core material.
I hope this helps.

Yes, RPStress and YoungTurk that is exactly what I'm doing.
Thanks for your suggestions.

You should be able use MIl-HDBK-23 to determine the loads on the face sheets and core. Then you can use MIL-HDBK-17 to analyze the laminate to determine failure points.
Mil-hdbk-17 vol III http:
IHS has Mil-HDBK-23 available. www.ihserc.com

Good luck!
