Wave tailoring in elastic and elastoplastic granular systems
This dissertation studies wave propagation in granular media with the objective of developing stress wave tailoring applications. Two mechanisms for wave tailoring are investigated: the first part focuses on energy dissipation in elasto-plastic granules and the second studies tunable wave …

Wave tailoring granular materials: effect of randomness and plane wave propagation
… in material and geometric properties on wave propagation behavior in 1D and 2D granular media. Results obtained for both 1D chains and 2D media show the kinetic energy amplitude decays with distance, with the rate of decay found to depend on the level of randomness and the distance from …

Elastic wave tailoring at the macro/micro/nano- scales using intentional strongly nonlinear coupling
In acoustics, wave tailoring refers to the manipulation of the propagation of waves or energy that are generated due to some form of dynamic loading. It includes real world examples ranging from impact mitigation to sensors and communication applications and is typically accomplished through the …

Developments in topology and shape optimization
… stress-constrained topology optimization; and a wave tailoring topology optimization. In shape optimization, the independent node movement approach, wherein finite element node coordinates are used directly as design variables, allows the most freedom for shape change and avoids the …
