Multi-axial fatigue numerical crack propagation in cruciform specimens [PDF]

, 2019
Two cracks, initiated from the opposite tips of a 45° inclined central notch, were considered in cruciform specimens made of Ti6246. A static load was applied along an arm of the cruciform specimen together with an alternating load (R=-1) applied along ...
