Abstract Scope This work presents a method for the design of architected materials made of bistable building blocks for desired dynamic behavior. With the advances of additive manufacturing, which has facilitated the fabrication of microstructures of materials, there has been an increasing interest in design of architected materials to obtain desired properties. Among these materials, bistable architected materials are of interest since they can exploit microstructural instabilities to exhibit extraordinary mechanical properties. These materials can be used for controlled trapping of elastic energy by reconfiguration into higher energy and stable deformed states. The instabilities in these metamaterials are very sensitive to the geometry of the structure. Therefore, in this work, we propose a method to design the microstructures of bistable metamaterials to obtain specific behavior. We demonstrate the effectiveness of the method via numerical examples.
