摘要：

The damage of composite interference-fit bolted structures is complex and challenging to study experimentally. Numerical simulation is necessary to reveal damage mechanisms, but macroscopic models based on homogenization hypotheses cannot simulate micro-scale failure processes. This paper analyses a CFRP single-lap interference-fit bolted structure, achieving precise micro-scale damage analysis through macro-micro information transfer using a micro-scale Representative Volume Element (RVE) model and a macro-scale finite element model, enabling strain transfer between scales.
