<p>Combining the continuously distributed dislocation technique (DDT) and the von Mises yield criterion, new double-crack and multi-crack models were established. The influences of multi-segment kinked micro-cracks and groups of kinked micro-cracks on the plastic behavior of the macro-crack were investigated. The results show that a smaller kinking angle of the micro-crack enhances its influence on the plastic deformation of the macro-crack, potentially leading to plastic zone fusion. Meanwhile, micro-cracks with smaller kinking angles exert a stronger attracting force on macro-crack growth, facilitating convergence between them. Furthermore, annularly distributed micro-crack groups demonstrate a more pronounced attraction on macro-crack propagation compared to linearly distributed micro-crack groups. The double-crack and multi-crack models established in this paper offer a theoretical framework for analyzing the plastic fracture behavior of metallic materials containing complex kinked cracks.</p>
