Crack growth resistance curves have been determined for crack-divider laminates in which layers of 2024T3 aluminum alloy are adhesively bonded to layers of 7075-T6 alloy. Results are compared with the fracture resistance of laminates consisting wholly of each material, the layer thickness being the
method has recently been developed for determining a nonlinear fracture toughness parameter defined by the relation where G, is the critical elastic strain energy rate as defined by Irwin. The C term is a function of the nonlinearity of the load-displacement test record and has been evaluated using
Tensile tests have been performed on replicated aluminum alloy foams of relative density between 4.5% and 8%. During the test the electrical resistance was measured with a four-point set-up and the displacements along the gage section were measured using a digital image correlation (DIC) technique.
