DOI: 10.1016/j.ijfatigue.2016.09.011
Abstract: Abstract Multiple fatigue cracks are prevalent in welded structures. Current fatigue assessment code procedures employ various simplifications in the treatment of multiple cracks that result in over-conservative life predictions. In this work, crack coalescence and… read more here.
