Data underlying the article: In-plane deformation measurements for validation of composite forming simulations

In-plane deformation measurements on press-formed parts from a unidirectional carbon-fiber reinforced thermoplastic composite material. Laminates with a cross-ply layup were formed over a dome geometry. The outer ply recieves a painted pattern before deformation and was subsequently digitized using photogrammetry after forming. The dataset includes the methodology used in calculation of the deformations. Additional analyses for a correction, the use of symmetries and precision analysis are also included.

本数据集针对单向碳纤维增强热塑性复合材料（unidirectional carbon-fiber reinforced thermoplastic composite material）的冲压成型构件开展面内变形测量。研究中采用交叉铺层（cross-ply layup）的层合板在穹顶几何模具上进行成型加工。成型前，外层铺层预先喷涂有标记图案；成型后，则通过摄影测量法（photogrammetry）完成数字化处理。本数据集包含变形计算所采用的完整方法体系，同时还收录了校正分析、对称性应用分析以及精度分析等补充研究内容。
