question about coordinate transformation# Computation - 科学计算

seems like a simple question:
Here is a solid element in Lagrange Coordinate System(CS).
I know now the stress and strain of it in local CS(element CS):
SIGMA[xx],
SIGMA[yy],
SIGMA[zz],
SIGMA[xy],
SIGMA[yz],
SIGMA[xz],
...
also geometry and points' coordinates, etc.
How could i build up the transform matrix to know global stress and strain,
Still more parameters required?
any fortran or C++ rountine for example?I am confussed of the tensor
transforming, would like to be concerte.
BTW: This probl
