The evaluation of embankment stresses by coupled boundary element - finite element method
… These advances were mainly in: 1) introducing higher-order elements, 2) developing effective solution schemes, 3) developing sophisticated means of modeling the constitutive behavior of geotechnical materials, and 4) introducing iteration techniques to model material non-linearity. This thesis, …

Finite element analysis of 3D electric machine problems
… implementation, which includes the use of higher-order elements and isoparametric elements. Since electric machines usually operate in a low frequency band, it is necessary to handle the low-frequency breakdown problem properly. In this thesis, we propose two possible solutions. One is to …

Nonlinear three-dimensional behavior of shear-wall dominant reinforced concrete building structures
… placed edge nodes and with variable edge orders (from linear to cubic) is developed in order to consider the amount and location of the main reinforcement at the edges and around the openings, and in order to use higher order elements where the stress gradients are expected to be high. The …

A Higher Order Accurate Finite Element Method for Viscous Compressible Flows
… (SU/PG) method is applied to higher-order finite-element discretizations of the Euler equations in one dimension and the Navier-Stokes equations in two dimensions. The unknown flow quantities are discretized on meshes of triangular elements using triangular Bezier patches. The …

An axisymmetric linear/high-order finite element for filament wound composite structures
The development of an axisymmetric linear by high-order finite element to model filament-wound structures is presented. The primary objective of this work was to develop a ’design code' to analyze filament wound spherical pressure vessels. In order to develop a design-oriented analysis capability …

Influences of Higher Order Modeling Techniques on the Analysis of Layered Viscoelastic Damping Treatments
… these models are compared against models with elements from C0 elements and a C1-capable element that matches tractions at material interfaces. It is shown that the time-honored modal strain energy method is a good indicator of modeling accuracy. To assess the effects of the MM assumptions on …

Modelling-based design of anisotropic piezocomposite transducers and multi-domain analysis of smart structures
… transducers, these properties are adopted in order to avoid the complexity of the piezocomposite microstructure. In the case of smart structures the accurate modelling of the actuation and the response of the structure is of primary importance. If classical structural finite elements are not …
