研究了温度和螺栓扭矩对航空连接性能的影响。根据ASTM D5961，采用钛螺栓和复合板进行单搭接接头。建立了一个基于有限元法的数值模型，计算了螺栓和复合材料板的应力。载荷-位移曲线，应力场，和诱导损伤显示，显着的，温度结合扭矩水平对关节的影响。结果发现，在接骨板中，所考虑的最大和最小扭矩水平均会产生高于临界阈值的损坏。在接头设计过程中应考虑到这一事实。
This study focuses on the analysis of influence of temperature and bolt torque on aeronautical joint behavior. A single-lap joint, according to ASTM D5961, with a titanium bolt and composite plates was considered. A numerical model based on FEM was developed to evaluate the stress in both bolt and composite plates. Load—displacement curves, stress fields, and induced damage showed, significantly, the influence of temperature combined with torque level on the joint. It was found that in the plate, both maximum and minimum levels of torque considered produced damage above critical threshold. This fact should be accounted for, during the design process of the joint.
