Abstract
The growing interest in additive manufacturing and printed materials has opened new possibilities for the development and application of Graded Materials (GMs). However, capturing the strength and fracture behavior of GMs presents challenges, as the extent to which classical theories for homogeneous materials apply remains uncertain. For example, it has been recently suggested that in the classical problem of a sharp wedge or crack loaded in-plane (mode I and/or mode II), the stress singularity can be mitigated by grading the elastic properties of the material near the notch tip according to a power-law distribution, E∼ r β. This suggests that sharp geometrical discontinuities can exist without causing sharp stress concentrations. Under these conditions, it is conceivable that structural optimization should aim to achieve uniform stress distribution or, more specifically, consistent strength throughout the material …
