Exact Riemann solution for the Euler equations with nonconvex and nonsmooth equation of state
This thesis is concerned with the solution of the Riemann problem for the Euler equations with nonconvex and nonsmooth equation of state. The main goal is to develop an exact Riemann solution by means of wave curve composition, which accounts for physically relevant effects such as composite waves …

On the formation of Friedlander waves in a compressed gas driven shock tube
… tests. The well-known initial structure of the Riemann problem eventually evolves into a shock structure resembling a Friedlander wave. In this thesis, we develop an analytical model to predict its key characteristics: location where the wave first forms, peak over-pressure, decay time and …

Spacetime damage-based cohesive model for elastodynamic fracture with dynamic contact
… an efficient patch-by-patch, advancing-front solution scheme with O(N) computational complexity. Per-element balance properties, local adaptive operations, and the use of Riemann fluxes provide to the SDG method the extreme accuracy and efficiency required to solve multiscale fracture …
