Nonlinear Waves in Composites and Snow: Constitutive Response

This lecture covers the detection of micro-damage in composites using nonlinear waves, the strain rate dependency in constitutive modeling of snow, and the visco-hyperelastic model for human brain tissue. It discusses experimental validation methods, dynamic shear and tension tests, and the comparison of Rivlin models. The presentation also delves into the mechanical characterization of gels, the validation of deformation states, and the development of a visco-hyperelastic model. The content includes a detailed analysis of high strain rate experiments, dynamic stress equilibrium, and the application of hyperelasticity in various materials.
