Abstract : Report Objectives: Damage Tolerance-To examine the effect of flaw size and stacking sequence on fracture stress (Pressure) and mode for graphite/epoxy cylinders and to predict these fracture stresses using coupon (Flat Plate) data; and To explore possible means of selectively reinforcing composite cylinders in order to arrest crack propagation. Aeroelasticity-To study the effect of bending-torsion stiffness coupling in advanced composites, on the aeroelastic flutter and divergence behavior of unswept and forward swept wings; and To explore aeroelastic behavior of wings at high as well as low angles of attack.
