Medium Density Fiberboard

Is there a material tag for MDF (medium density fiberboard) in Mechanica? ANSI has a standard for MDF, and I would like to run some tests using Mech. on this material. If not, what are the steps needed to create a new material tag? Do I create a file? Do I download MDF from a database? I can even test the material myself as I am a graduate student with the appropriate testing facilities at my disposal. Possible Major Project/Thesis.
