摘要：
In this article, the notched strengths of asymmetric woven hybrid laminates were studied by using both experiment and the finite element-based point stress criterion (FEMPSC). It was experimentally shown that the notched strength decreases with the increase of hole radius for all the laminates machined by water jet cut, drilling, and milling. Particularly, it is noted that the notched strength of specimens of the same hole size made by water jet cut is obviously higher than those made by both drilling and milling, due to stress redistribution. The results also indicate that the notched strengths predicted by FEMPSC agree well with the experimental data, with only a 4% margin of error.
