Check out the book "Roark's Formulas for Stress and Strain" by Young and Budynas. It has a chapter dedicated to loading of flat plates with tables to address stresses in the plate for the case you are describing.

Or, you could do what everyone else does and assume it spans in the short direction and check it as a simple ended member.
Sometimes the easiest solution is the best solution.

Good point Jed...guess it depends on how exact you need to get.
