[HTML][HTML] Influence of in-plane shear on kink-plane orientation in a unidirectional fibre composite
D Wilhelmsson, LP Mikkelsen, S Fæster… - Composites Part A …, 2019 - Elsevier
Kink-band formation is the governing failure mechanism for compressive failure of fibre
reinforced composites. Here, kink-plane orientation, describing the direction of kink-band
formation, is studied using X-ray computed tomography (CT). Unnotched unidirectional
specimens with off-axis angles ranging from 0° to 20° are tested in compression. The
measured compressive strength is found practically constant for off-axis angles between 0°
and 10°. For an off-axis angle of 15° the compressive strength drops dramatically. CT-results …
