“…That implies that the middle of the crack front will propagate first. Based on this, Ho and Tay [21] concluded that the convex shape would evolve into the concave one. However, since the mode mixity is relatively constant along the crack front, regardless of the initial shape, it follows that the convex shape would have to "go through" the straight form first, before changing to the concave one.…”

“…The work of Ho and Tay (2009) delves into a profound exploration of the influence of initial delamination shapes on the mechanics of 3D interfacial delamination within the IC packages, considering the three distinct front shapes, concave, straight, and convex. Notably, their findings reveal intriguing insights into the maximum energy release rate (ERR) associated with each of these front shapes [21]. Their findings provided valuable insights into optimizing the design strategies and materials to mitigate delamination risks in electronic packaging and related applications.…”

This study delves into the analysis of interface crack propagation originating from a right-angle corner along the bonding plane between the two plates composed of dissimilar materials. The research explores three distinct crack front shapes: concave, triangular, and convex (quarter-circle). The obtained results, meticulously presented in this paper, offer valuable insights into the nature of the crack propagation along these geometries. The findings elucidate that in the case of a convex crack front, the edges demonstrate a significantly accelerated propagation compared to the rest of the crack front. Conversely, for the triangular and concave crack fronts, the central region experiences faster propagation compared to the edges. These revelations lead to a generalized conclusion regarding the stability of different crack front shapes, highlighting the triangular crack front as the most stable configuration in this context. The implications of these observations provide essential knowledge for understanding and managing crack propagation in composite structures, offering potential applications in various engineering domains.
