(i) In ambient environment, increase in R dips ( frac{dc}{dN} ), although the effect is not as high as in case I laminates.
Also, at same R in case I laminates, fatigue life in ambient environment is higher than in aqueous environment at lower R and vice versa at higher R.
In corrosive environment, N⊗ in case I laminates is found to increase with increase in R which is contrary to expectations since ( frac{dc}{dN} ) increases with increase in R in such an environment.
Since plain aluminum alloy specimens, series P1 and P2, exhibited crack growth on both their sides, their behavior is compared with series 1 of case I laminates that was tested under similar conditions, i.e., R of 0.1 in ambient environment.
In comparison with case I laminates in the same environment, the maximum laminate fracture toughness values are higher, and the maximum ( frac{dc}{dN} ) values are of nearly similar magnitudes.
The data of case I laminates under different Rs are presented in the form of series 1 to 9: series 1 to 4 in ambient environment, series 5 to 7 in aqueous environment, and series 8 to 9 in corrosive environment.

New structural efficiency diagrams are presented, showing that current design practice incurs additional mass because: (i) laminate balancing axes are not aligned with principal loading axes and (ii) principal loading ratios vary within a part with fixed ply percentages.
The paper then presents results of experimental investigations carried out on pultruded GFRP material made of polyester and E-glass fibres at two different scales: (i) laminate and (ii) full-scale profile.
Even though the matrix behavior becomes highly ductile, the degree of retention of mechanical properties is quite high, and the hole factor is virtually unchanged as temperature increases in Q-I laminates.
I printed up one copy of a high resolution photo – I laminated it for ease of use and transfer.
I laminated these sheets and told my Hadrian's walkers to bring a cracker toy to exchange.
