Fig. 9From: Recent advancements on the phase field approach to brittle fracture for heterogeneous materials and structures(from [37])a Geometry of the tensile test of a bi-material system; b curve which separate the crack penetration, crack single deflection and crack double deflection cases; transition from double deflection (c) to single deflection (d) and crack penetration (e) for a brittle interface \((\Pi _2\rightarrow 0)\) varying the ratio \(1/\Pi _1\). The contour plots scale is a dimensional vertical displacement Back to article page
