It is fascinating to see how natural materials like teeth enamel, bone and nacre possess a very high stiffness and strength in spite of the fact that they are composed of minerals mostly. Studies have shown the reason for this aberration as the presence of weaker interfaces with intricate interlocking architectures at microscopic levels in these materials. Inspired by the architecture of these materials, micro-architectured sutures with jig-saw like geometry is being studied in this research study. The main focus of this study is to examine the effects of friction co-efficient and interlocking angles of the jig-saw tabs on pullout strength, fracture toughness and energy absorption. We are using Phase-Field Fracture model to study these effects in ABS (acrylonitrile-butadiene-styrene) material. We will also simulate the fracture of the interlocking tabs when the interlocking angle goes beyond a certain limit.
