About SSPX
A program to calculate strain/strain rate from displacement/velocity data in two and three dimensions. SSPX is a full fledged inverse modeling program to calculate best fitting deformation tensors given displacement or velocity vectors at a minimum of three points in two dimensions, or four points in three dimensions.

SSPX works equally well on small deformation problems (i.e. infinitesimal strain), and large deformation problems (i.e. finite strain).

SSPX is free for academics.
