Abstract
The out-of-plane fold is a common defect of composite materials during
the manufacturing process and will greatly affect the compressive strength as well
as the service life. Making it of great importance to investigate the influence of
out-of-plane defects to the compressive strength of laminate plates of composite
materials, and to understand the patterns of defect evolution. Therefore, the strip
method is applied in this article to create out-of-plane defects with different aspect
ratios in laminated plates of composite materials, and a compressive performance
test is conducted to quantify the influence of out-of-plane defects. The result
shows that the compressive strength becomes weaker with a greater aspect ratio.
When the highest aspect ratio is set to 0.12 in the experiment, the compressive
strength reduces by 36.1%. Then we establish a 3-D progressive damage model
based on continuum mechanics, and write it into the UMAT subroutine together
with the 3-D Hashin criteria and the non-linear degradation criteria of materials.
3-D solid modeling is performed for the samples with an out-of-plane fold based
on ABAQUS, and progressive damage analysis is conducted to acquire the inplane evolution process of initial failure strength with different laminates. The
experimental results agree well with the simulation results.
