Abstract:

The utility of line force fields in computer simulations of lattice defects is discussed. These fields are shown to provide a facile method for introducing realistic flexible boundary conditions on simulated atomic crystallites. The pertinent elastic fields for line force arrays lying parallel to the tip of a planar crack are presented. The method has been successfully applied to a study of hydrogen embrittlement of alpha-iron. The usage of this type technique is particularly important in the case where nonequilibrium phenomena--such as unstable crack growth--are studied. Modified author abstract
