A hybrid parallel framework for computational solid mechanics
A novel, hybrid parallel C++ framework for computational solid mechanics is developed and presented. The modular and extensible design of this framework allows it to support a wide variety of numerical schemes including discontinuous Galerkin formulations and higher order methods, multiphysics …

The State-based Peridynamic Lattice Model and Reinforced Concrete Structures
Continuum mechanics is the leading tool used in computational solid mechanics. Continuum mechanics, however, assumes a materials body to be continuous, represented by analytical functions. This assumption is unrealistic for reinforced concrete structures, which become discontinuous as cracks form. …

A vertex based discretisation scheme applied to material non-linearity within a multi-physics finite volume framework
… for the solution of small strain, quasi-static, Computational Solid Mechanics(CSM) problems involving non-linear material behavior, specifically materials described by an elasto-visco-plastic constitutive relationship and a von-Mises yield criterion. The motivation is to contribute the non-linear …

Meshless methods: theory and application in 3D fracture modelling with level sets
… cracks in 3D remains a challenging topic in computational solid mechanics since the geometry of the crack surfaces can be difficult to describe unlike the case in 2D where cracks can be represented as combinations of lines or curves. Secondly, crack evolution requires numerical methods that …

Multiscale modelling of sutures in a high-performing biological protective structure: the turtle shell
… is not well understood. We address this by using computational models of turtle shells where special attention is paid to the influence of the network of sutures. Additionally, we elucidate the structure-function relationship using parametric studies varying the suture geometry. Computational …

Computational Modeling and Validation of the Deformation and Failure Response of Human Metastatic Vertebrae
… In this thesis, we propose a comprehensive computational framework for the modeling and validation of the deformation and failure response of human metastatic vertebrae. First, we develop an image-based pipeline for the generation of patient-specific finite elements (FE) models starting from …

Simulation of deformation and fracture in very large shell structures
… have increased the limits of three-dimensional computational solid mechanics, structural elements remain essential in the practical design of very large thin structures such as aircraft fuselages, ship hulls, automobiles, submarines, and pressure vessels. In many applications, fracture is a …

Aerothermal and aeroelastic response prediction of aerospace structures in high-speed flows using direct numerical simulation
… flight regime. In this thesis, a high-fidelity computational approach is used to examine the fluid-structural response of aerospace structures in high-speed flows. The method is applied to two cases: one involving a fluid-thermal interaction problem in a hypersonic flow and the other a …
