Abstract

An interlaboratory testing programme to evaluate the rising displacement test for stress corrosion crack (SCO growth investigations was carried out within the framework of the "Measurements and Testing" programme of the European Community under BCR contract nr. MATI CT 930038. The contribution of the NLR to the project consisted of testing of precracked Double Cantilever Beam (DCB) Specimens made from the high strength aluminium alloy 7010-T651 under constant displacement and by continuous immersion in substitute ocean water. The results of these static tests were to be used as reference data for the dynamic rising displacement tests carried out by other participants in the project. Further, additional static tests were carried out by the NLR using alternate immersion in substitute ocean water. The results of these tests were compared with those ot 7U1U T651 plate from another batch of material tested previously at the NLR.
