复合材料由于其高比强度和耐腐蚀等优点逐渐在船海领域得到广泛应用，而加筋板是船海结构中的基本组成单元，研究复合材料加筋板的脱粘损伤行为以及脱粘缺陷对结构屈曲特性和承载性能的影响具有重要意义。基于渐进损伤方法，考虑层间和层内损伤建立数值分析模型，通过与轴压屈曲模型试验对比，验证本文方法的合理性；研究含有贯穿脱粘缺陷的复合材料加筋板轴压损伤分层演化和压溃行为，并分析其结构承载性能变化和响应特性。
Composite materials have been widely used in marine engineering due to their advantages of high specific strength and corrosion resistance, and the stiffened panel is the basic component of ships and offshore structures. It is of great significance to investigate the debonding behaviors of composite materials stiffened panel and the influence of debonding defects on the structural buckling characteristics as well as bearing capacity. Based on the progressive damage method, the numerical analysis model is established in consideration of the damage between and within layers, and the numerical method proposed by this paper is validated against the axial buckling model test. The delamination and collapse behaviors of composite material stiffened panel with debonding defects are studied, and the bearing capacity variation and structural response characteristics are analyzed.
