Formulations for incremental elastic-plastic analysis and the consolidation of porous media
… for the solution of the problem, mostly based on Newton-Raphson methods using an explicit scheme for the integration of the constitutive relations. The procedures in current use can be criticised in that they are essentially heuristic, and they are not fully linked to the governing mechanical …

Optimal design of water distribution networks with reliability considerations
… user. This is followed by a resume of current methods and algorithms for the analysis of networks and a detailed examination of the previous work on network optimisation and reliability. Three main algorithms exist for the analysis of water networks. These are the Hardy-Cross methods, the …

Three-dimensional non-linear finite element analysis of reinforced concrete beams in torsion. Reinforced concrete members under torsion and bending are analysed up to failure. A non-linear concrete model for general states of stress including compressive strength degradation due to cracking is described.
… used are the standard and the modified Newton-Raphson methods. Line searches have been implemented to accelerate convergence. The numerical integration has been generally carried out using 15 point Gaussian type rules. Results of a study to investigate the performance of these rules show …

Ionic separation in electrodialysis : analyses of boundary layer, cationic partitioning, and overlimiting current
… scheme including the fixed point iteration and Newton Raphson methods, the P[subscript II] equation was successfully solved for the ionic transport in the space charge and electroneutral regions as well as their transition zone. Above the limiting current, the sum of the ionic charge in the …

On Enforcing Maximum Principles and Element-Wise Species Balance for Advective-Diffusive-Reactive Systems
This dissertation aims at developing robust numerical methodologies to solve advective-diffusive-reactive systems that provide accurate and physical solutions for a wide range of input data (e.g., Péclet and Damköhler numbers) and for complicated geometries. It is well-known that physical …
