Error estimation and adaptivity in deformable solid dynamics
… in numerical simulations of deformable solid dynamics . For that, we start from the semidiscrete equations of motion and analyze the conditions that an estimator must satisfy to compute accurate results. With them, two typical error estimators are analyzed. Later, we propose a novel …

From a thin membrane to an unbounded solid : dynamics and instabilities in radial motion of nonlinearly viscoelastic spheres
In this thesis, a theoretical investigation of the dynamic motion of spherically symmetric bodies is presented, considering nonlinear viscoelastic material responses. To explore the stability thresholds of the dynamic motion and to compare them with available formula for the quasi-static limit, the …

Multi-physics Diffuse Interface Methods For Computational Material Modelling
… of materials, including fluids, elastoplastic solids and multi-phase mixtures. This is achieved by both amalgamating existing separate diffuse interface methods for multi-phase reactive fluids and solid dynamics, as well as extending the model with a set of novel methods to allow for the …

Numerical Methods for Fluid-Solid Coupled Simulations: Robin Interface Conditions and Shock-Dominated Applications
… algorithms for coupling computational fluid dynamics (CFD) and computational solid dynamics (CSD) solvers, and the use of these solvers for simulating fluid-solid interaction (FSI) problems involving large deformation, shock waves, and multiphase flow. The dissertation consists of two parts. …

Effects of Elevated Intracranial Pressure on a Cerebral Vein Model
… project, the effects of elevated ICP on the hemodynamics and structural dynamics of a diploic vein were considered. This was done by performing transient coupled fluid-structure simulations on a segment of an intracranial vein that sought to replicate the ICP surge experienced during …

Finite volume modelling of low speed structural impact problems
Two investigations are described in this thesis on the common theme of applying finite volume methods to simulate structural impact problems. The first investigation is the application of the Eulerian Finite Volume Method (EFVM) to simulate the low-speed impact of ductile materials. Simulation …

The Runge-Kutta Taylor-SPH model, a new improved model for soil dynamics problems
… this thesis is focused on numerical modeling of dynamics behavior of dry soils in the framework of small and large deformation theory and of dynamics behavior of saturated soils in the framework of small deformation theory. A numerical code has been developed to analyze such behaviors and …
