Nonlinear waves in hyperelastic solids

Krishnaswamy Ravi-Chandar
Temple Foundation Professor

Polyisoprene rubber exhibits a strain-induced stiffening response upon monotonic loading as well as hysteretic response upon unloading, induced by the kinetics of crystallization. This is further influenced by the high strain-rates experienced in impact problems. These effects of material behavior translate to a rich range of nonlinear wave phenomena including the formation and propagation of shocks and phase boundaries. In this presentation, these nonlinear wave phenomena will be explored through a series of specially designed experiments, with appropriate diagnostics to obtain spatio-temporally resolved kinematic measurements, and then through numerical simulations.


Krishnaswamy Ravi-Chandar, received his Ph.D., in Aeronautics from the California Institute of Technology. He was awarded the Murray Medal by the Society for Experimental Mechanics in June 2004 and the Drucker Medal of the ASME in 2015. He is the Editor-in-Chief of the International of Fracture. He served as President of the International Congress on Fracture (2005-2009), and President of the American Academy of Mechanics (2011-2012). He serves as Chair of the US National Committee for Theoretical and Applied Mechanics (2019-2020).
