Data for: Optimizing parallel section length for small tensile specimen with fabrication non-uniformity in thickness

The raw data of the tensile curves for QP980 steel, which are numerically tested by finite element method using thin small specimens with different parallel section length.

本数据集包含QP980钢的拉伸曲线原始数据，所有数据均采用不同平行段长度的薄壁小试样，通过有限元法（Finite Element Method）进行数值测试得到。
