Numerical study on fiber waviness defect and sensitivity analysis of the parameters

The presence of fiber waviness defects is well-known to reduce the compressive strength. A FE model was established and results failure load mode were compared with test demonstrate validity accuracy. influence two parameters L offset Angle θ defect studied. simulation show that compression increases increasing at constant A/H for convex concave fold by 33.0% 20.1% respectively, but there no significant effect on within 5%.
