摘要: Abstract The propagation of a semi-infinite line defect, contained in an infinite square-cell lattice is considered. defect composed particles lighter than those the ambient and it assumed this propagates with constant speed. Dispersion properties are related to waves generated by propagating defect. In order determine these properties, Wiener–Hopf technique applied. Additional features, localisation along also identified. Analysis dispersion relations for lattice, from kernel function inside equation, carried out. solution equation presented case when external load applied corresponding energy flux at infinity.
