Determination of Constitutive Equation Parameter Using Finite Element Polycrystalline Model.

Finite Element-Based Model for Crack Propagation in Polycrystalline Materials∗

In this paper, we use an extended form of the finite element method to study failure in polycrystalline microstructures. Quasi-static crack propagation is conducted using the extended finite element method (X-FEM) and microstructures are simulated using a kinetic Monte Carlo Potts algorithm. In the X-FEM, the framework of partition of unity is used to enrich the classical finite element approxi...

Finite Element Methods for Convection Diffusion Equation

This paper deals with the finite element solution of the convection diffusion equation in one and two dimensions. Two main techniques are adopted and compared. The first one includes Petrov-Galerkin based on Lagrangian tensor product elements in conjunction with streamlined upwinding. The second approach represents Bubnov/Petrov-Galerkin schemes based on a new group of exponential elements. It ...

SAW Parameter Extraction Using Finite Element Analysis

Surface acoustic wave devices apart from being small, rugged and reliable can also be used as wirelessly interrogatable and completely passive devices in hostile environments. As complex signal processing functions can be performed with a simple structure through the variation of electrode patterns they can power wireless sensors and actuators in a secure manner. It is important to develop exac...

Determination of long-term slip rates of faults in the eastern part of Iran plateau using finite element kinematic model

Since Iran plateau is located in the Alpine-Himalayan Orogenic belt, it is recognized as a region with a high seismic risk. Thus, investigation of geodynamic activities of the faults, their slip rates and corresponding deformation fields is very important for quantification of possible seismic risk in this region. The aim of this study is to analyze the tectonic features of eastern part of Iran...
