Non-Linear Finite Element Method Simulation and Modeling of the Cold and Hot Rolling Processes
A nonlinear finite element model of the hot and cold rolling processes has been developed for flat rolling stock with rectangular cross section. This model can be used to analyze the flat rolling of cold and hot steel rectangular strips under a series of different parameters, providing the rolling …

Enhanced Anisotropic Bounding Surface Model: Implementation and Simulation of Excavation in Soft Cohesive Soils
… enhanced anisotropic bounding surface model with non-associative flow rule, based on the anisotropic critical state theory and bounding surface plasticity. The model has exhibited a great potential to realistically simulate the mechanical behavior of cohesive soils, in non-linear finite element …

Wellbore instability mechanisms in clays
… wellbores drilled in Ko-consolidated clays using non-linear finite element method (FEM) and effective stress soil models to characterize the behavior of clay and unconsolidated shale formations. Two constitutive models are used: Modified Cam Clay (MCC; Roscoe and Burland, 1968), and MIT-E3 …

Screw piles as offshore foundations : Numerical and physical modelling
… capabilities in different soils. In this thesis, non-linear Finite Element Method (2D & 3D) was used to investigate the screw pile behaviour under lateral, vertical and combined loading. The FEM was also used to investigate the optimum spacing of the helical plates and the geometry effects on the …
