………..where we get shaking under control!Keywords: Elastodynamics, nonlinear waves, band gaps, transformation methods, resonance phenomena, negative stiffness systems
The primary objective of this research is to design materials with adaptive, tunable and extreme elastodynamic properties using principles from biology and geophysics that will transform applications in impact resistance, wave modulation, and earthquake engineering. Current efforts focus on theoretical understanding of the nature of mechanical band gaps, elastodynamic response of layered systems, novel applications of transformation elastodynamics, and modeling of negative stiffness structural elements.
