The aim of this work is to study the size-dependent elastic interaction of a screw dislocation with an elastic isotropic layered semi-infinite matrix using molecular dynamics analysis. The analytic solutions of complex functions of a screw dislocation in the matrix and in the thin layer are solved by means of applying complex potential approach in conjunction with the techniques of the image method...
We investigate the interaction between edge crack and edge dislocation as well as concentrated force and point heat source. The stress intensity factors at the edge crack tip and the image forces acting on the edge dislocation are calculated. The influence of the concentrated force, point heat source and edge dislocation on the shielding and anti-shielding effects to edge crack as well as the glide...
