FR-4 PCB material specs

I am trying to perform a modal and dynamic analysis on a printed circuit board (PCB) and have found it difficult to obtain reliable material specifications. My initial Frequency analysis indicated displacements of several meters. Can anyone point me to reliable material specifications for the FR-4 (epoxy laminate) material and how to accurately model a 6 layer PCB with 2 1 oz. interior copper layers and .5 oz. outside copper layers?
