A generalized criterion for fatigue crack growth in additively manufactured materials – Build orientation and geometry effects
Source abstract
Abstract
Abstract The effect of material anisotropy on the fatigue crack growth (FCG) behavior in additively manufactured materials is investigated by developing an energy-based criterion. The criterion is developed based on the strain energy density concept in an anisotropic domain and considers the effects of specimen geometry by introducing the T-stress in the solution. The proposed criterion is examined by predicting the FCG experimental results available in the literature for 3D-printed Inconel 718 and 17-4PH stainless steel components built in different orientations. It is found that both material anisotropies resulting from build orientation and the T-stress play remarkable roles in FCG behavior of 3D-printed components.
