Summary on Grant Application Form
The proposed work is in the area of computational mechanics. The aim of this project is to develop a numerical formulation capable of correctly modelling the far-field boundary for two-phase media, and its effect on the time-dependent interaction between a structure, and the underlying local soil. As a result of this research, an improved understanding of stress wave transmission in a two-phase medium will be gained. This would lead to safer and more cost-effective designs by engineers operating in the field of geodynamics (including seismic analysis). This is particularly important for high-capital construction projects such as nuclear reactor installations, dams, offshore platforms, and large-span bridge structures. Consequent improved confidence in risk assessment would allow communities living near these safety-critical structures to feel more secure.The research will be achieved by extending the highly attractive existing single-phase scaled boundary finite element method, into a two-phase coupled consolidation approach for both static and dynamic conditions. The developed formulations will be programmed and incorporated into a finite element program, and made available via the Internet. Validation will be achieved by comparing with closed-form and extended mesh solutions.
