Complete characterization of sink-strengths for mutually 1D-mobile defect clusters: Extension to diffusion anisotropy analog cases.

•Considering 1D-diffusers, most sink-strength are unknown which prevents rate-equation prediction of dislocation loops growth.•New limiting cases can be proposed by properly extending the analogy with 2D random walk with respect to a fixed sink.•These new expressions are implemented in rate-equation cluster dynamics and compared to kinetic MonteCarlo simulations.
