Modeling of a biological material nacre: Multi-objective optimization model

Nacre is an inner layer of seashells that has a remarkable combination of stiffness, strength, and toughness. Engineers are inspired to mimic it to create engineering composites with properties not available in current materials. Toward designing and realizing a bioinspired nacre, a search for some best combination of tablets material, matrix material, and system geometry is needed to obtain optimal mechanical properties. In this work, a multiobjective optimization model is developed based on a genetic algorithm optimization method. The multi-objective optimization problem solved results in a set of optimal solutions that the designers can select according to their preferences.
