Three-dimensional anisotropic elasticity - an extended Stroh formalism

Tom Ting and I have recently developed a method of extending Stroh's anisotropic formalism to problems in three dimensions. The unproofed paper can be accessed at http://www-personal.umich.edu/~jbarber/Stroh.pdf . It is particularly convenient for problems where boundary conditions are imposed on the plane, such as contact problems, dislocations and crack problems.
