Abstract Climate‐induced desiccation cracks exhibit a hysteresis behavior, referred to as crack dynamic (CDH), where they display different geometric characteristics during the drying and wetting phases at constant soil water content. This phenomenon has complex effect on slope stability, an aspect often overlooked in analytical numerical methods. In this study, we conducted experimental analyses provide new insights into effects of CDH stability. A series laboratory experiments cracking under drying‐wetting cycles were performed. The testing results used develop validate extended dual‐permeability model. proposed model was integrated set stability using finite element method. show that causes greater fluctuations dynamics increases retention cycles. Neglecting leads underestimation dry conditions overestimation wet conditions, with these discrepancies becoming more pronounced progress. Furthermore, changes mechanical properties soil, transitioning relatively stable zones regions prone localized instability. These unstable present significant challenges for accurately analyzing managing slopes cracked layers. Monitoring groundwater local development after heavy rainfall events is essential mitigating collapses.
