Homework Help: Prove that transversly isotropic materials have 5 independant elastic constants

  1. Oct 16, 2011 #1
    1. The problem statement, all variables and given/known data
    So I need to prove that transversly isotropic materials have 5 independent elastic constants. I can prove that an orthotropic material has 9 independent elastic constants. I need to use the transformation matrix to show that some of the 9 mentioned components are equal for TI materials but I don't know how! Can you guys please help me or just introduce a source to me where I can find the mathematical proof? I really appreciate it.

    2. Relevant equations

    3. The attempt at a solution
