IV.3.4.3 Properties of the laminates defined in an ESAComp file

The second example, defined in file “testCla2.rb” illustrates the use of iterators. For each laminate defined in a ClaDb, several properties are printed. These properties are printed in several directions by rotations of $30^o$. Part of the program is reproduced below:

def diagnostic(edfName,os)

   db=ClaDb.new
   db.Id="testDB"
   db.readEdf("test.edf")

   db.each_laminate do |lamId,lam|
      (0..360).step(30) do |i|
         theta=1.0*i

         os.printf("\nlaminate = \"%s\" -- theta = %g\n\n",lamId.to_s,theta)

         os.printf("\n   Stiffness matrix : \n\n");
         lam.write_ABBD(os,theta)
         os.printf("\n");

         ...
      end
   end
end

os=File.open("test.txt","w")
diagnostic("test.edf",os)
os.close
