alleryStart learning →A CROSS-PLY laminate consists only of:
APlies at +45° and −45°
BPlies at 0° and 90° only (no off-axis angles)
CPlies at random angles
DPlies all at 0°
Answer & Solution
Correct answer: B. Plies at 0° and 90° only (no off-axis angles)
**Cross-ply:** only 0° and 90° plies.
Naturally A_16 = A_26 = 0 (no off-axis terms) and, if symmetric, also D_16 = D_26 = 0. Used when bidirectional in-plane stiffness is wanted with simple design.
