纤维能量释放率对开孔层压板承载能力影响研究

Study on the effect of fiber energy release rate on the bearing capacity of porous laminated plate

在航空领域,为了分析复合材料层板破坏行为,工程技术人员往往基于Abaqus有限元复合材料分析平台,建立复合材料层板有限元破坏分析模型。文章系统地研究了纤维增强的体能量释放率绝对层压板初始破坏和最终破坏载荷的影响,给出了参数设置建议。

In the field of aviation, in order to analyze the damage behavior of the composite board, the engineering tech. nician is often based on the Abaqus finite element composite material analysis platform, and the finite element damage analysis model of the composite material layer is established. The paper systematically studies the effect of fiber-rein. forced body energy release rate on the initial failure and ultimate failure load of the laminate, and gives the suggestion for parameter setting.
