How to apply the same material property on several parts in one time

Hello, Everyone

             Recently, I have use SIMULIA in R2012X  to simulate a complex structure which is combined of  nearly 30 parts. When I start to apply the material property on the structures, I have to apply the same material property one part by one part.

             Will you know some method to do this step in one time ?

                                                                                                             Thanks

                                                                                               Best Wishes
