Abstract

Crack extension behaviour in the heat affected zones of welded structures differs significantly from crack propagation in a homogeneous material. The crack in a geometrically symmetric precracked specimen under symmetric loading will deviate from its initial plane, due to changes in the properties of the material caused by the heat treatment during welding.
