You can always go to define>materials>other and select modify show material and enter the properties for your wood there. If your working with plastic hinges youll have to define properties from define>hinge screen.
For materials properties Id check out a book on mechanics of materials, they tend to have a decent list of wood types and material properties in the back of the book. You can define your own hinge with the stress strain curve that you are looking for. Since you are defining a hinge you really are dealing with moment vs rotation behavior and not stress strain but the trend in the curve should be what you want in stress strain.
