Innovations of advanced materials have been at the core of most engineering technologies, devices and systems. Composite laminates in particular have been extensively employed in many major and advanced industries including aircraft, maritime transport, and automobiles. Failure in composite structures is critical and often complicated, and that is the consequence of the evolution of and interactions among the constitutive fracture events (e.g., matrix cracking, fibre/matrix debonding, delamination, fibre breakage, fibre kinking). Accurate prediction of progressive failure in composite laminates is crucial for the development and design of most lightweight components and structures. This paper, for the first time, outlines a critical review on the developments and recent applications of regularized phase field models for failure problems in composite laminates and structures. Fundamentals of the phase field models are introduced and the developments of the regularized model from different aspects for the modeling are reviewed. Phase field models as well as the modeling strategies from different levels of idealization, i.e., microscopic, mesoscopic and macroscopic length scales are presented. The realization of existing widely used models such as cohesive zone model, plasticity, and damage initiation criterion and energy decomposition into the phase field model is also addressed. Typical applications of the phase field models in composite laminate modeling are discussed.

综述相场模型,基本原理及其在复合材料层压板中的应用

先进材料的创新一直是大多数工程技术,设备和系统的核心。尤其是复合层压板已广泛应用于许多主要和先进的行业,包括飞机,海上运输和汽车。复合结构的破坏是至关重要的,而且通常很复杂,这是本构性断裂事件(例如,基体开裂,纤维/基体剥离,分层,纤维断裂,纤维扭结)演变和相互作用的结果。对于大多数轻质部件和结构的开发和设计,准确预测复合材料层压板的渐进式破坏至关重要。本文是第一次 概述了正则相场模型在复合材料层压板和结构中的失效问题的发展和最新应用的重要评论。介绍了相场模型的基本原理,并从建模的各个方面回顾了正则化模型的发展。提出了不同理想化程度的相场模型以及建模策略,即微观,介观和宏观长度尺度。还讨论了现有广泛使用的模型的实现,例如内聚区模型,可塑性和损伤起始准则以及能量分解到相场模型中。讨论了相场模型在复合材料叠层建模中的典型应用。介绍了相场模型的基本原理,并从建模的各个方面回顾了正则化模型的发展。提出了不同理想化程度的相场模型以及建模策略,即微观,介观和宏观长度尺度。还讨论了现有广泛使用的模型的实现,例如内聚区模型,可塑性和损伤起始准则以及能量分解到相场模型中。讨论了相场模型在复合材料叠层建模中的典型应用。介绍了相场模型的基本原理,并从建模的各个方面回顾了正则化模型的发展。提出了不同理想化程度的相场模型以及建模策略,即微观,介观和宏观长度尺度。还讨论了现有广泛使用的模型的实现,例如内聚区模型,可塑性和损伤起始准则以及能量分解到相场模型中。讨论了相场模型在复合材料叠层建模中的典型应用。介绍了介观和宏观长度尺度。还讨论了现有广泛使用的模型的实现,例如内聚区模型,可塑性和损伤起始准则以及能量分解到相场模型中。讨论了相场模型在复合材料叠层建模中的典型应用。介绍了介观和宏观长度尺度。还讨论了现有广泛使用的模型的实现,例如内聚区模型,可塑性和损伤起始准则以及能量分解到相场模型中。讨论了相场模型在复合材料叠层建模中的典型应用。
