Abstract Scope |
We present our latest research in formulating a computational design strategy for mitigating damage resulting from high-strain rate loading events. It is well-known that unprecedented properties can be achieved by tailoring nonlinearities derived from designed mesostructure. Several examples of materials with designed nonlinearity have shown outstanding promise for shock and impact mitigation. Yet, the examples of mesostructure-derived effective material nonlinearities are few and far between. Two primary challenges exist: (1) nonlinearity dramatically expands this unintuitive design space compared to linear material problems, introducing a plague of local minima and non-uniqueness; (2) even if we had an answer to (1), it is not guaranteed that the best nonlinear material can be manufactured. The researchers of the Center for DREAMS (Dynamically Responsive Emergent Architected Material Systems) in the UC system develop a computational approach via mathematical optimization to readily discover the mesostructures of architected materials with desired effective nonlinearity. |
