Abstract
The fatigue failure kinetics for welded joints of low-alloyed steel is inve stigated by analyzing the displacement vector field under high-cyclic loadi ng. Failure accumulation in the heat-affected zone at the mesoscale is foun d to possess a multi-stage character that is associated with the formation and evolution of mesostructure deformation and fragmentation. Identified ar e the pertinent parameters that described the mechanical state of welded jo ints under load. (C) 2000 Elsevier Science Ltd. All rights reserved.
