Training data for cantilever beam with transverse cracks

This dataset contains the input and target data generated by using a mathematical relation to predict frequency changes for cantilever beams affected by transverse cracks.
The input data is as follows:
- the column represents the first eight relative frequency shift values for out-of-plane bending vibration modes.
- each column represents the damage location and severity, after the hole beam is scanned, we produce cracks also at the fixed end to simulate imperfect boundary conditions.

本数据集收录了基于数学关系生成的输入数据与目标数据，用于预测受横向裂纹（transverse cracks）影响的悬臂梁（cantilever beams）的频率变化。
输入数据如下：
- 每列对应面外弯曲振动模态（out-of-plane bending vibration modes）的前八项相对频移（relative frequency shift）值；
- 每列代表损伤位置与损伤程度；在对开孔梁（hole beam）完成扫描后，我们还会在固定端预制裂纹，以模拟非理想边界条件（imperfect boundary conditions）。
