Experimental and numerical investigations of wrinkle effect on failure behavior of curved composite laminates

Compared with flat laminates, curved composite laminates are more susceptible to wrinkle defects which must be considered in the design and structural integrity assessment. Combined experimental testing and numerical simulations were carried out in this paper to investigate the influence of wrinkles on the failure behavior of L shaped laminates. Special lay-up and forming processes were used to generate the pre-defined wrinkle profiles, and...
