If we have a n X n matrix [H] whose all elements are a function of x, whats is the best procedure to find the root(s) of Determinant [H(x)]? How to handle zero(s) and singularity(s) both accurately?
How can we identify the the experimental results are correct? Lots of students have asked me, Sir, I'm not getting the results as per the manuscript? In that case, what will be the procedure to...

I need to model an anisotropic material in which the Poisson's ratio ν_12 ≠ ν_21 and so on. Therefore, the elastic compliance matrix wouldn't be a symmetric one. In ANSYS APDL, for TB,ANEL...
