Abstract

This special issue entitled “Quantitative visualization testing techniques applied to civil engineering structures and materials” follows the organization of a series of thematic workshops entitled “Techniques d'Imagerie pour la Caracté risation des Matériaux et des Structures du Génie Civil” (image-based techniques for the characterization of materials and structures in civil engineering). The different editions took place in France in the cities of Clermont-Ferrand (March 20–21, 2014), Grenoble (March 10–11, 2016) and Champs-sur-Marne (April 4–5, 2019), bringing together about 50 PhD students, post-doc, early career or senior researchers who gave oral or poster presentations in the field of the experimental mechanics applied to civil engineering structures and materials. The present special issue illustrates how much the quantitative measurement experimental techniques in that research field have progressed and diversified within the last decade. Among the quantitative testing techniques used in the presented papers, one may want to highlight the various full-field or multipoint measurement methods: 2D and 3D Digital Image Correlation, Grid method, Particle Image Tracking, Particle Imagery Velocimetry, Digital Volume Correlation, Sampling moiré, Reflection photoelasticity, Optical fibre sensors, among others. These test methods are applied to heterogeneous materials: concrete, fibre-reinforced concrete, textile-reinforced concrete, granular materials, etc., from the microscopic or nanoscopic scale to the metre or decameter scale when applied to concrete bridges or masonry walls in this present special issue. Applications concern various environmental conditions such as high temperatures, different moisture contents, or loading conditions like high strain-rates testing. The underlying damage mechanisms are investigated by different methods like X-ray microtomography, synchrotron radiation or rapid neutron tomography. The wealth of experimental evidence brings better understanding of the mechanical behaviour of these civil engineering materials and structures and leads to substantial progress in the identification and the development of predictive modelling using Finite or Discrete Element, damage, cohesive zone or mixed-mode fracture models. We would like to acknowledge the contribution from many people which made this special issue possible. We wish to express our warm thanks to our reviewers for their time and efforts in reviewing papers and the authors for their work in submitting and revising their manuscript.

应变特刊:应用于土木工程结构和材料的定量可视化测试技术
这期题为“应用于土木工程结构和材料的定量可视化测试技术”的特刊是在组织了一系列题为“Matériaux和Génie civil结构成像技术”的专题研讨会之后发行的(土木工程中用于材料和结构表征的基于图像的技术)。不同的版本在法国的克莱蒙费朗(2014年3月20日至21日)、格勒诺布尔(2016年3月10日至11日)和马恩河畔尚普(2019年4月4日至5日)举行,汇集了大约50名博士生、博士后、早期职业或高级研究人员,他们在土木工程结构和材料实验力学领域进行了口头或海报演示。本期特刊展示了该研究领域的定量测量实验技术在过去十年中取得了多大的进步和多样化。在本文中使用的定量测试技术中,人们可能想强调各种全场或多点测量方法:2D和3D数字图像相关、网格法、粒子图像跟踪、粒子图像测速、数字体积相关、采样莫尔、反射光弹性、光纤传感器等。这些测试方法适用于非均质材料:混凝土、纤维增强混凝土、织物增强混凝土、颗粒材料等,当应用于本特刊中的混凝土桥梁或砌体墙时,从微观或纳米尺度到米或十米尺度。应用涉及各种环境条件,如高温、不同的含水量或高应变速率测试等负载条件。通过不同的方法,如X射线显微成像、同步辐射或快速中子断层成像,研究了潜在的损伤机制。丰富的实验证据使人们更好地了解了这些土木工程材料和结构的力学性能,并在识别和开发使用有限元或离散元、损伤、内聚区或混合模式断裂模型的预测建模方面取得了实质性进展。我们要感谢许多人作出的贡献,使这个特别问题成为可能。我们衷心感谢审稿人在审阅论文方面付出的时间和努力,感谢作者在提交和修改稿件方面所做的工作。我们还感谢《应变杂志》前主编Fabrice Pierron教授在整个过程中的指导和支持。祝你阅读愉快,充满灵感,

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.
