Instabilities in Stress Corrosion and the Transition to Brittle Failure
Daniel KoehnJochen ArnoldBjørn JamtveitAnders Malthe-Sørenssen
Studies on the dissolution of stressed crystals have shown that stress corrosion can lead to roughening of interfaces. The corrosion pattern develops due to gradients in elastic energy along a...
