This report presents our approach for calculation of the Task. Our numerical code THAMES is the three-dimensional finite element simulator of fully coupled processes. First, we defined the input data for THAMES from the supplied properties of FEBEX bentonite. After calibrations of some parameters such as thermal vapour diffusivity, the analysis that treats fully coupled thermal, hydraulic and mechanical processes was carried out.

The influence of triple-junctions upon experimental Ge diffusion profiles (850 to lOOOC) in nanocrystalline Si was investigated using three-dimensional finite element simulations. It was found that triple-junction diffusion was not negligible in nanocrystalline Si made of 40nm wide grains. Ge triple-junction diffusion coefficient could be described by ...

Experimental data and three-dimensional finite element simulations of the flow in two different profile dies for glass run seal of a car are presented. The flow in one of the two dies, a plate die, is found to be highly unbalanced. Using a feeder plate in the second die (a stepped die configuration) the flow at the exit of the die was properly balanced. 

Based on the control volume approach and using the three-dimensional finite element formulations for heat conduction with convection and momentum balance for non-Newtonian fluids presented earlier, Turng and Kim [10] and [17] developed a three-dimensional mold filling simulation using 4-noded tetrahedral elements. The nodal control volumes are defined by surfaces that connect element centroids and sides as schematically depicted in Fig. 9.33. 

Fig. 20 Simulation of the propagation of the laser-induced stress wave as a function of distance from the irradiation spot. A three-dimensional finite element analysis program has been employed. The simulation shows that the highest probability for delamination is at the interface just behind the irradiation spot. This prediction is verified in the irradiation of nonannealed polymer samples on Suprasil...

Abstract motif is a three-dimensional finite-element code developed to simulate groundwater flow, heat transfer and solute transport in deformable fractured porous media. The code has been subjected to an extensive verification and updating programme since the onset of its development. In this paper, additional verification and validation works with an emphasis on thermo-hydro-mechanical processes are presented. The verification results are based on cases designed to verify thermo-hydro-mechanical coupling terms, and isothermal and non-isothermal consolidations. A number of validation case studies have been conducted on the code. Example results are repotted in this paper. 

The MOTIF code is a three-dimensional finite-element code capable of simulating steady state or transient coupled/uncoupled variable-density, variable- saturation fluid flow, heat transport, and conservative or nonspecies radionuclide) transport in deformable fractured/ porous media. In the code, the porous medium component is represented by hexahedral elements, triangular prism elements, tetrahedral elements, quadrilateral planar elements, and lineal elements. Discrete fractures are represented by biplanar quadrilateral elements (for the equilibrium equation), and monoplanar quadrilateral elements (for flow and transport equations). 

Abstract A newly developed numerical simulator of two-phase flow using three-dimensional finite element method is presented in this paper. It is described that the fundamental simultaneous equations, the deduction to implicit pressure explicit saturation formulation and their finite element discretization method. Furthermore, its practical application to the numerical simulation project of predicting Horonobe natural gas product is also introduced. 

Recognizing the importance of the coupled hydro-mechanical effects on the performance of civil engineering structures involving fractured rocks, the stress-flow coupling mechanism of the dam-foundation system at Longyangxia site was simulated using a three-dimensional Finite Element code, supported by two visco-elastic constitutive models to represent the time-dependent material behaviour of the dam concrete and the foundation rock. The calculated results were concord with the measured ones and helped to interpret the causes of this continuous displacement at the 13" dam section of the Longyangxia hydropower project, towards the left bank.

A simple theoretical model based on composite beam theory associated with the traditional strength of the materials was developed to describe the behaviour of the panels in the elastic range. A three-dimensional finite elements analysis on the whole panel was also performed to simulate its flexural behaviour. 

Blow molding is complicated by the complex stress field set up in the materials when the parison is inflated. This amounts to a biaxial stretching of the molten polymer and it is difficult to obtain material data under these conditions so that simulation may be performed. Despite this, much work on the inflation stage has been done, mostly with the aim of determining the final thickness distribution. Recently parison inflation has been simulated using three-dimensional finite elements and with remeshing of the parison as it inflates to minimize error from element distortion. ... 

All technology discussed here is based on the assumption that the plastic part is thin walled and makes use of the Hele-Shaw approximation. Three-dimensional finite element analysis (3D/FEA) eliminates this requirement. In so doing, it introduces a new class of components to simulation. With 3D/FEA it is possible to. simulate the molding of parts for which a midplane is not available. Typically, such parts are chunky— some examples are given in Fig. 7.64. Many parts... 

A mathematical relationship between the DOC profile across the cross-section of a pultruded part and the die-heater temperatures was established by Li et al. (2002b).The relationship was employed to optimize the die-heating profile such that a near-uniformly cured component could be obtained finally. The algorithm was implemented for simulation of pultrusion process using the three-dimensional finite element/nodal control volume (FE/NCV) approach developed by Joshi and Lam (2001).

Here, the three-dimensional finite-element procedure used by Gifford [19] to solve three-dimensional free-surface problems which include inertia will be reviewed. Previous results of simulations showing the effect of Reynolds number on extrudate swell of Newtonian liquids from a square die are discussed and compared to new results from a rectangular die. Limiting die swell solutions at infinite Reynolds number are discussed and the effect of the aspect ratio of the rectangle on these limiting values is presented. The effect of wall slip on die swell from the square die is also considered.
