Hi
You need the elastic constant for aluminum plus the crystal symmetry of that material for your command to work
Here is how the elastic constant should look like:

The elastic constant for your material you can find published

Maybe you need to look to some basic concepts symmetry in elastic constants, symmetry related to stress and strain, crystal symmetry etc, your matrix is incomplete and wrong
Something like
