In “Computational Modeling of the Mechanical Behavior of 3D Hybrid Organic-Inorganic Nanocomposites,” Dr. Xiaowei Zeng and his co-workers describe a study in which a three-dimensional hybrid nanocomposite was analyzed using the cohesive finite element method. This model contained hard mineral nanograins bonded by a relatively soft and thin organic adhesive layer to mimic the ultrastructure of biological ceramics such as bone and nacre. The cover figure shows damage initiation in the thin layers of the adhesive phase.
