Nonlocal elasticity and dislocation image force due to cracks
Fundamental field equations of nonlocal elasticity are presented. With these equations, the image force on a screw dislocation due to a crack is analyzed using the conformal map** technique. Two cases are c...

Interaction of a circular second-phase particle and a screw dislocation in nonlocal elasticity
The stress field, interaction energy and image force of a screw dislocation near a circular second-phase particle in a matrix are investigated analytically in nonlocal elasticity. With the result obtained we f...

Nonlocal interaction of a dislocation with a crack
Based on the classical stress analysis, the stress field of a screw dislocation near a semi-infinite crack is investigated by a conformal map** method. The classical image force on the dislocation due to the...
