提出了一种预测复合材料螺栓连接破坏开始时轴承应力的简单三维方法。该方法明确考虑了由于垫圈和层压板之间的摩擦而产生的负载。建立了不同破坏模式下作为锚杆夹紧函数的破坏准则，并将模型预测结果与试验数据进行了比较。参数化研究表明，衬垫与层合板的摩擦系数、衬垫尺寸以及衬垫圈的性能对接头性能的影响。
A simple three-dimensional approach is presented for predicting bearing stress at failure onset in a composite bolted joint. The approach allows explicitly for the load carried as a result of friction between the washers and the laminate. Failure criteria are developed for different failure modes as functions of bolt clamp-up and then the predictions of the model are compared with experimental data. A parametric study shows the effects on joint per formance of the coefficient of friction between the washers and the laminate, washer size and the properties of the laps in the joint.
