本文首次对二维无网格随机网格法（MRGM）的位移和应变场的全场测量进行了系统的实验验证。尽管基于先前进行的虚拟数据支持的敏感性分析，MRGM已经显示出非常有希望的准确性，性能和易于应用的特点，但直到现在还没有广泛的实验验证。这项工作填补了这一空白，并根据从复合材料试件的裸眼拉伸实验中收集的应变片数据提出了初步的验证结果。并与有限元分析结果进行了对比研究，进行了应变和位移的现场验证。ASME版权所有©2011
This paper presents the first systematic effort for the experimental validation of the 2D Meshless Random Grid Method (MRGM) for the full field measurement of displacement and strain fields. Although the MRGM has been demonstrating very promising characteristics of accuracy, performance and ease of application based on previously conducted sensitivity analysis supported by virtual data, extensive experimental validation was not available until now. This work comes to fill this gap and presents preliminary validation results against strain gauge data collected from open hole tension experiments of composite specimens. In addition, strain and displacement field verification is performed by comparison studies with finite element analysis results.Copyright © 2011 by ASME
