Project description:
There are many industrial applications that require the use of computer models to understand the nature and behavior of shock waves in solids due to intense short-term perturbations such as instantaneous contact-impact loading and/or material rapid impact. temperature changes. For example, failure mechanisms of a material under a ballistic shock Of interest to UKAWE, 3D printing is critical to the design of elastomeric multi-materials.
Current shock physics simulation codes, based primarily on industry-optimized Computational Fluid Dynamics (CFD)-based methods, are capable of handling shocks across the entire spectrum of CFD applications. However, the success of this methodological approach has not been replicated in other areas of science, such as large deformation solid dynamics and its relation to other physics and new materials.
Building on recent work by the review group, this project will explore a new computational framework using the Arbitrary Lagrangian Eulerian (ALE) formalism written as a system of first-order conservation laws. The conservation-type ALE formulation, which exhibits striking similarities to that used by the CFD community, has inspired researchers to adopt conventional CFD algorithms in the new context of Computational Solid Dynamics. One of the main contributions of this work is that the physical strain gradient can be obtained by multiplying its decomposition into two auxiliary strain gradient tensors, both calculated by additional first-order conservation laws. Most importantly, the conversion of the new ALE conservative formulation to systems of Lagrangian and Eulerian mixed-based conservation laws will be shown. A Finite Volume/Intermittent Galerkin/Smooth Particle Hydrodynamics algorithm with Riemann-based upwind stabilization will be used for spatial discretization using embedded software.
The hired PhD candidate will be a member of an active research group working on the development and application of advanced computational methods for large strain solid dynamics, dynamic fracture/contact and computational multiphysics.
