Abstract

The bonded composite repair has proven to be an effective method for addressing crack damage propagation. Numerous studies have employed experimental and simulation techniques to demonstrate the repair performance through the composites. These studies have explored various parameters related to bonded composites, such as size and properties, to enhance repair effectiveness. However, one aspect that has not been thoroughly investigated is the impact of fiber orientation within the composites. Therefore, the current work investigates the effect of the fiber direction of the composite patch bonded on a thin plate under plane stress conditions. Three types of fiber orientation of composite patch have been considered. In this investigation, the finite element method was used to determine the stress intensity factor using the ANSYS commercial code. The research findings showed that the fiber direction influenced the mitigation of stress intensity factor. This study is particularly important for designing the composite patch based on the fiber direction.

基于纤维取向的复合材料薄板对缓解修复板应力强度因子的影响:有限元研究
事实证明,粘接复合材料修复是解决裂纹损伤扩展的有效方法。大量研究采用实验和模拟技术来证明复合材料的修复性能。这些研究探讨了与粘接复合材料有关的各种参数,如尺寸和性能,以提高修复效果。然而,尚未深入研究的一个方面是复合材料中纤维取向的影响。因此,目前的工作研究了在平面应力条件下,粘合在薄板上的复合材料贴片的纤维方向的影响。研究考虑了复合材料贴片的三种纤维取向。在这项研究中,使用 ANSYS 商业代码,采用有限元法确定了应力强度因子。研究结果表明,纤维方向会影响应力强度因子的减缓。这项研究对于根据纤维方向设计复合材料贴片尤为重要。
