Abstract

The advent of digital image and volume correlation has attracted wide use in fracture mechanics. The full‐field nature of digital image and volume correlation allows for the integration of computational fracture mechanics to analyse cracked samples quantitatively. This review provides a comprehensive overview of current methods used to extract fracture properties from full‐field displacement data. The term full‐field fracture mechanics is introduced to highlight the uniqueness of using inherently noisy experiential data to extract fracture properties. The review focuses on post‐processing‐based approaches rather than integrated approaches, as these have less limitations and are more commonly employed. There are four approaches that are discussed in extracting fracture properties from experimentally computed displacement data: field‐fitting, integral, crack‐opening and cohesive zone modelling approaches. This is further developed to discuss problems associated with using digital image and volume correlation to extract properties, including application examples.

从数字图像和体积相关位移数据中提取断裂特性：综述

数字图像和体积相关技术的出现在断裂力学中得到了广泛应用。数字图像和体积相关技术的全场性质允许将计算断裂力学与定量分析裂纹样品相结合。本综述全面概述了目前用于从全场位移数据中提取断裂属性的方法。引入 "全场断裂力学 "一词是为了突出使用固有噪声的经验数据提取断裂属性的独特性。本综述侧重于基于后处理的方法，而不是综合方法，因为这些方法的局限性较小，也更常用。本文讨论了从实验计算的位移数据中提取断裂属性的四种方法：现场拟合法、积分法、裂缝开裂法和内聚区建模法。在此基础上，进一步讨论了使用数字图像和体积相关性提取属性的相关问题，包括应用实例。

期刊介绍： Strain is an international journal that contains contributions from leading-edge research on the measurement of the mechanical behaviour of structures and systems. Strain only accepts contributions with sufficient novelty in the design, implementation, and/or validation of experimental methodologies to characterize materials, structures, and systems; i.e. contributions that are limited to the application of established methodologies are outside of the scope of the journal. The journal includes papers from all engineering disciplines that deal with material behaviour and degradation under load, structural design and measurement techniques. Although the thrust of the journal is experimental, numerical simulations and validation are included in the coverage. Strain welcomes papers that deal with novel work in the following areas: experimental techniques non-destructive evaluation techniques numerical analysis, simulation and validation residual stress measurement techniques design of composite structures and components impact behaviour of materials and structures signal and image processing transducer and sensor design structural health monitoring biomechanics extreme environment micro- and nano-scale testing method.
