Residual stress is inherent in any fiber reinforced composite, created by the laminates processing route and high levels of anisotropy. The aim of this article is to provide an up to date review of the current state of the art in experimental techniques for the determination of residual stress in thermosetting fiber reinforced composites. Residual stress is considered at a micro‐mechanical, macro‐mechanical, and global scale as each require specific techniques to investigate and offer their own unique challenges to the designer. Many advances have been made in the experimental determination of residual stress in fiber reinforced composites since the last comprehensive review of the topic by Shokrieh in 2014. However, more work still needs to be done to develop a method that is applicable to all cases and can be applied as a universal standard. It remains a significant challenge to experimentally determine residual stress in thermosetting composites.

纤维增强热固性复合材料中的残余应力：测量技术的回顾

残余应力在任何纤维增强复合材料中都是固有的，这是由层压板的加工路线和高水平的各向异性引起的。本文的目的是提供用于确定热固性纤维增强复合材料中残余应力的实验技术的最新进展的最新信息。残余应力是从微观，宏观和全局的角度来考虑的，因为每种都需要特定的技术来研究并向设计人员提出独特的挑战。自2014年Shokrieh对纤维增强复合材料的残余应力进行实验确定以来，在测定残余应力方面取得了许多进展。但是，仍然需要做更多的工作来开发一种适用于所有情况的方法，并且可以用作通用标准。
