Because the thickness of the blade varies, we need to set the material via commands. First, we will create a command that governs the material properties of the outer surface of the blade. To create a command, right click on the Outer Surface surface body, and select Insert > Commands. In the command prompt, insert the following:

Panel

/prep7 !Call the Preprocessor

et,matid,181 !Specify the element type, shell 181
keyopt,matid,3,2 !Use full integration
mpdel,all,matid !Delete all previously assigned material properties
tbdel,all,matid !Delete all previouly assigned tabular data

MP,EX,1,33E9 !Define Young's Modulus: X Direction
MP,EY,1,33E9 !Define Young's Moduls: Y Direction
MP,EZ,1,33E9 !Define Young's Modulus: Z Direction

MP,PRXY,1,0.3 !Define Major Poisson's ratio XY
MP,PRYZ,1,0.3 !Define Major Poisson's ratio YZ
MP,PRXZ,1,0.3 !Define Majoy Poisson's ration XZ
