Materials with Designed Nonlinearities: Enabling a New Generation of Stress Wave Transformation
Abstract
Material nonlinearity is potentially one of the most transformative, yet underexplored, methods for controlling stress wave propagation. The objective of this AFOSR Young Investigator Program proposal is to answer the following fundamental open questions: how can we create materials with any desired material nonlinearity?; what material nonlinearity is the best for a given dynamic loading scenario?; and what situation-specific nonlinearity enables the translation of a given dynamic input to any desired dynamic output? To answer these questions, we will utilize additively manufactured, microstructured lattice materials as a flexible, structural toolbox for developing and studying materials with designed, effective material nonlinearities stemming from microstructural geometric nonlinearities. This study will truly be revolutionary, causing a paradigm shift away from studies of dynamical systems containing specific material nonlinearities, and will open a new class of ultralight materials with tailorable nonlinearity and extraordinary stress wave transformation properties.
