2D Experimental UPV Data from Five Isolated Unit Bricks

The datasets in each sheet contained the x and y coordinates along with the corresponding Spatial Dynamic Elastic Modulus on the plane of an isolated unit brick. These modulus values were computed from the Ultrasonic Pulse Velocity (UPV) measurements taken through the thickness of the brick at specific points.各工作表中的数据集包含独立单块砖平面内的x、y坐标，以及对应的空间动态弹性模量（Spatial Dynamic Elastic Modulus）。这些模量值通过在指定测点沿砖厚度方向采集的超声波脉冲速度（Ultrasonic Pulse Velocity，UPV）计算得到。
