Finite element analysis three-dimensional

Many developers of software for finite-element analysis (18) provide drafting of pipelines and associated flow analysis. These companies include Algor, McAuto, MacNeal-Schwindler, and ElowDesign. In software, in-house developed pipe fittings are modularized and isometric views of the piping systems with three-dimensional detailing are now commonplace. 

Computer aided design (CAD)/computer-aided manufacture (CAM) programs have been developed to carry out the necessary calculations. One current system known as Polyflow is offered by a Belgian organisation (Polyflow SA). Polyflow can be used to calculate three-dimensional flow and die swell, using finite element analysis. Other systems are available. 

Within the present method a pure matrix/inclusion type micro-topology is assumed (no interwoven structure can be represented). Hence, a sudden change of the properties occurs, when the matrix material changes from alumina to nickel. The IMT-method as implemented performs a fully three-dimensional analysis on the micro level independently of the global finite element analysis option. 

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...

In the three-dimensional finite-element analysis of below-grade structures which must serve to ensure, with a high degree of confidence, that systems or components they house can fulfill lOCFRlOO-related radionuclide control functions under design basis conditions torsional effects are inherently accounted for in the analysis so no artificial torsional loads will be imposed.

The determination of stresses, strains and displacements in a multi-layer system is conducted by computer programs using, typically, three methods (a) the multi-layered elastic analysis, (b) two-dimensional (2D) finite element analysis and (c) three-dimensional (3D) finite element analysis. 

A number of cruciform joints of rectangular hollow section were fabricated with adhesive gusset plates (Fig. 8.15). Hollow sections of two different sizes were used, and some of the specimens were subjected to accelerated ageing prior to testing in tension. The structural behaviour of these joints was also predicted by non-linear, three-dimensional, finite-element analysis. Very good agreement was obtained between the experimental and predicted load-displacement behaviour. 

Finite element analysis. The strength of the beam-to-column connections were analyzed using simple hand computations and finite element three-dimensional plate analyses. Stress concentrations around the exterior access hatches and internal access ports were first analyzed using basic strength of materials and available equations (Young and Budynas, 2002) and then further examined using finite element analyses. 

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. 

Modeling is the method of choice for analyzing passenger car cord-reinforced rubber composite behavior. Large scale three-dimensional finite element analysis (FEIA) improves imderstanding of tire performance, including tire and tread behavior when the rubber meets the road. ... 

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... 

While a full scale experiment to investigate the seismic behavior of a real structure together with SSPW is hard to conduct, an analytical study with a well verified computational RC and soil model (Maekawa et al. 2003) can serve as an alternative to capture the overall efficiency of SSPW. In this study, the authors use a full three dimensional nonlinear finite element analysis of soil-structure-pore water systems. The applicability of the system was verified by shaking table experiments of top-heavy piles embedded in a liquefiable model foundation (Maki et al. 2004, 2005, Mohammed and Maekawa 2012 Mohammed et al. 2012a). Using this analytical platform, the effects of SSPW as a seismic countermeasure for the rafted pile foundation is discussed with regard to the base shear induced in the RC multistorey superstructure and its overall stability. Both cases of drained and undrained soils are considered in the analysis to clarify the potential effect of soil liquefaction. 

Zhang Zhang (2010), referring to the modified criterion, conducted a three-dimensional elasto-plastic finite element analysis in order to propose an empirical expression of cohesion (c) and friction angle (( )) for layered rocks, which are transversely isotropic.
