Abstract
The structural response of laminated composite beams with off-axis matrix cracks is analyzed in this study. For that, a damage mechanics-based multiscale approach using a 2D finite-element-based cross-section analysis is developed. By using this approach, it is shown how the thickness and orientation of cracked plies and the cross-section geometry affect the degradation level of the beam stiffness properties. Beams with thin-walled box and symmetric airfoil cross-sections made of symmetric multidirectional laminates are analyzed in this study in order to get a better understanding of the structural response of damaged wind turbine blades.
