Abstract
Using the anisotropic theory of elasticity and a semi-atomistic Peierls model, the core energies and core tensions of dislocations in f.c.c. and h.c.p. metals have been calculated. All the results were expressed in terms of Fourier expansions. A simple algorithm allowed the determination of the core energies and core tensions of individual Shockley partials which form the perfect dislocations in close-packed planes.
