The code implements Muskhelishvili's complex function approach to calculate 2D stress intensity factors (modes I+II) from crack tip displacement fields. Surface displacements can be used with a plane stress elastic model. The code uses power/Fourier series expansion and a conformal mapping of an ellipse onto a circle. Fortran complex intrinsics are used in the code.


18-JAN-2017: release 1.0. However, the code, documentation and tests date from 2003-2006, with minor modifications since then.
