针对现有计算KunIC的公式和试验方法较为复杂的现象，通过对紧凑拉伸形式构件断裂试验的试验数据进行拟合，得出了求解KunIC的简便计算公式。采用得到的计算公式进行KunIC值计算，得出的数据与试验数据KunIC值进行对比，结果表明，两者相对误差小于7%。运用该公式计算KunIC值可大大简化计算过程。

The existing theoretical formulas and testing methods forKunICare complex. A simple formula to getKunICwas obtained by analyzing and fitting the data from compact tension specimen fracture tests. Using this simple formula to calculateKunIC, and the obtained values were compared with the experimental figures. Results show that the relative errors are less than 7%. So using this formula to calculateKunICcan greatly simplify the calculation process.
