“…Figure 13 also shows that the models with higher area fraction of pillars have higher inelastic deformation. Analytical studies by Begley et al [60] on a brick and mortar structure show that increasing the mortar strength will increase the ultimate strength of the material [60]. Increasing the area fraction of shear pillars has a similar effect on ultimate strength, as strengthening the mortar part in brick and mortar structure, which causes higher strength for the multilayered materials with a similar aspect ratio of platelets.…”

“…Modeling by Begley and co-workers [53,54] suggests that further improvements are possible. In theory, with a mortar yield strength of 50 MPa, ceramic bricks measuring ≈20 × 1 µm with a strength of ≈1 GPa, and interfacial sliding displacements of ≈75 nm, a twofold increase in strength and toughness should be achievable.…”

“…With the assumption of uniform shear stress distribution, a critical platelet aspect ratio was reported that distinguishes the platelet versus matrix failures. Begley et al 19 lifted the assumption of uniform shear stress and introduced different failure mechanisms for composites with a plastic matrix and uniform distribution of identical platelets. More recent studies proposed characteristic overlap lengths for elastic and plastic composites with uniform distribution of identical platelets 20 .…”
