The effect of free edges on inter-laminar performance of curved laminates

Numerical analysis of the effects of wrinkles in the radius of curvature of L-shaped CFRP specimens on unfolding failure

“…Wisnom [10] evaluated the distribution of interlaminar tensile stress through the width of curved specimens and highlighted free edge effects. This result corroborates the works of Fletcher et al [11,12]. Sun and Kelly [13,14] were among the first to study damage modes in cross-ply curved specimens in four-point bending tests.…”

Experimental and numerical analysis of unfolding failure of L-shaped CFRP specimens

“…Avalon and Donaldson [26] present experimental results where the thickness dependence does not appear when no compressive fibre failure is observed. Kim et al [27] and Fletcher et al [28] show the importance of edge effects in the failure of the specimens. Premature failure can be induced by stress concentration close to the edges [29][30][31][32].…”
