摘要

本工作的动机是展示一个以具有中斜坡区域的锥形夹层结构为代表的测试文章的案例研究，以降低全尺寸结构的认证成本。此外，这项工作为用于认证目的的负载增强因子的标准化提供了一个令人信服的案例。因此，本工作的开展是基于对具有制造缺陷和冲击损伤的试验件的定义，为符合静态和损伤容限要求，采用损伤无增长方法。得到的结果显示了降低认证开发风险和成本的良好策略。

Composites sandwich structures certification: A case study

The motivation of this work is to show a case study represented by a test article in tapered sandwich structure with a mid-ramp region in order to reduce certification cost of the full-scale structure. Also, this work provides a compelling case for the standardization of Load Enhancement Factor for certification purposes. Therefore, the development of this work is based on the definition of the test article with a manufacturing defect and impact damage, for compliance static and damage tolerance requirements with damage no-growth approach. The results obtained showed a good strategy to reduce risk and cost of the certification development.
