Abstract Not only the development process will be seriously affected, but also it will cause a serious cascading effects when the core developers in open source software turnover. From the dynamic perspective to explore the impact by core developer turnover, and taking effective measures to protect them will promote emergence of innovation. From the perspective of complex network, taking AngularJS as an example to identify the core developers by the method of multi-attribute decision. Then we build the load capacity model to study the cascading failures by core developers turnover. The study found that the close collaboration between core developers and the core developers who occupy an important position in the network turnover will lead to seriously cascading failures; What's more, developers with larger initial workloads turnover will cause more serious cascading failure phenomenon by secondary propagation.
