The invention relates to a method for test data reduction of composite intralaminar failure mode. A method to utilize the results from a series of FEM models to develop a master derivative of compliance curve. The use of the unique master curve resolves the test data variability issue caused by fitting the compliance curve individually. The analytically derived derivative of compliance curve eliminates the needs to take the derivative of compliance and therefore the derivative computation error no longer exists. By applying the existing solution and the solution as disclosed and claimed herein to the same set of the raw test data, it is found that data scatter is significantly reduced. 本发明涉及用于复合材料层内失效模式的测试数据简化的方法。种方法利用来自系列FEM模型的结果形成合规性曲线的主导数。使用独特的主曲线解决了由单独拟合合规性曲线造成的测试数据波动问题。分析得到的合规性曲线的导数消除取合规性的导数的需要并且因此不再存在导数计算误差。通过将现有的解决方案和本文中所公开且要求保护的解决方案应用于相同组的原始测试数据，发现数据离散显著地降低。
