| Popis: | Inspired by design motifs driving the balanced combination of rigidity, strength, and toughness in biological materials, this paper presents 3D computational modeling and simulation of an interface-enriched hybrid nanocomposite mimicking nacre’s ultrastructure. In this architectured material model, stiff mineral tablets are bonded by relatively soft and ductile organic matrices placed in the junction and interlayer space of the microstructure. Finite element analysis of this staggered multilayered model material is conducted using an in-house developed software package in which thin organic interfaces are represented by a generalized cohesive interface zone model. The computational model is validated against experimental measurements of stress–strain curves of nacre in tension. Subsequently, the deformation/toughening mechanisms and failure modes are discussed in tension and compression loading conditions. As an important microstructural feature, the effect of tablet aspect ratio on the elastic modulus of the composite is discussed. The role of the interlayer organic matrix on damage-induced tensile instability and compressive buckling in slender composite models is elucidated. |
