Fatigue and residual strength tests were done on doubler specimens consisting of an ARALL3 (3/2) laminate with a bonded-on fingertip doubler. The primary objective was to determine the effect of fatigue crack length on the residual strenght and delamination onset stress for this type of specimen. The specimens were precracked to variable crack...

Fatigue crack growth and residual strength tests were done on ARALL2 (2/1) laminates with bonded-on doublers. The main test variables were the shape of the doubler (square and fingertip) and the thickness of the doubler (0.5 and 0.8 mm). All coupons had a starter notch in the outer aluminium face sheet of the ARALL2 laminate at the edge of the...

Residual strength tests were performed on ARALL panels consisting of ARALL3 (3/2) laminates with bonded-on doublers. In particular, the effect of the doubler geometry (shape and thickness) on the residual strength was investigated. Prior to residual strength testing all panels were fatigue loaded to create a realistic type of damage, i.e. cracks...

Fatigue tests were carried out on Redux and FM 123/5 bonded specimens at various stress levels, temperatures (RT to 65 C) and low and high test frequencies. Observations were made on the type of failure (bond line failure or sheet failure) and the significance of the adhesive squeezeout for crack nucleation. An analysis of the data and a...

The effects of strain rate and temperature on the fracture behaviour of three structural adhesives (Redux 775, Metlbond 328 and EC 2216) were investigated using Double Cantilever Beam specimens. The test results were presented as critical elastic energy release rate data (G) to investigate whether this parameter could be used to characterize me...

This report presents results of residual strength calculations, carried out on cracked panel configurations of various designs and provided with bonded stiffeners. The calculations were carried out using the computer program BOND. The results of these calculations are compared with results of residual strength tests, performed on panels of...

The influence of sheet thickness (2 mm and 10 mm) and the influence of laminating (5x2 ram) on the fatigue crack growth properties of the aluminium alloy AL 7010-T 73651 were investigated. Both constant amplitude loading and flight simulation loading were applied. All 2 mm and 10 mm thick sheets were machined from a 150 mm thick plate, i.e....

Fracture toughness measurements were carried out to test the ageing behaviour of three adhesives in different environments. It was possible to compare and evaluate adhesives and surface pretreatments. It is doubtful whether the derived R-curves could be used for residual strength calculations in certain environments. Phosphoric acid anodizing...
