复合材料节点往往是复合材料结构中最薄弱的环节。在本文中，我们提出了一个基于屈服应变比的损伤区理论的修正版本。我们使用这个框架来预测各种粘接接头的失效载荷。制造并测试了具有八种不同粘合剂长度和四种粘合剂厚度的厚铝-铝接头试样。采用损伤区比法可以预测不同粘接长度的强度，误差在15.4%以内。此外，使用损伤区比方法，预测的接头，具有不同的胶粘剂厚度的强度在16.3%以内。(C)2009爱思唯尔有限公司版权所有。
Composite joints are often the weakest elements in composite structures. In this paper, we propose a modified version of the damage zone theory based on the yield strain ratio. We use this framework to predict failure loads for various adhesive joints. Thick aluminum-to-aluminum joint specimens with eight different adhesive lengths and four adhesive thicknesses were manufactured and tested. The strengths of different adhesive lengths could be predicted to within 15.4% using the damage zone ratio method. In addition, the strengths of joints that feature different adhesive thicknesses were predicted to within 16.3% using the damage zone ratio method. (C) 2009 Elsevier Ltd. All rights reserved.
