Architected materials composed of instability-based unit cells have been exploited in energy dissipation/absorption applications.One stability-based unit cell type that comprises slender beams can experience geometrical nonlinearities under small forces.Although reusability provided by these materials is attractive to engineering applications, the intrinsic Dual Inlet 5 Way Water Valve drawback of this mechanism is the low load-carry capacity.

Here, we attempt to increase the capacity of instability-based architected materials by inducing material nonlinearity of metallic materials.Through experimental tests and numerical simulations, this work investigates the plastic deformation of metallic architected materials using curved beams (MAM-CB) and their resulting energy dissipation capacity.We first investigated the mechanical properties of various Paleo Supplements MAM-CB unit cells, and finally studied the tradeoff between energy dissipation and fatigue life by embedding a geometrical gradient.

In addition, we presented a method to enhance the energy dissipation capacity of a conventional structure by adapting MAM-CB units to form a new hybrid structural device.Furthermore, this method is showcased by using MAM-CB units under a possible scenario in seismic engineering, aimed to develop novel damping components with enhanced and customizable energy-dissipating properties.Our study paves the way for applying architected materials as augmented structures to strengthen the performance of the existing structures.
