the development of yielded or failure zone due to an engineering construction is a subject of study in different disciplines. in petroleum engineering, depletion from and injection of gas into a porous rock can cause development of a yield zone around the reservoir. studying this phenomenon requires elasto-plastic analysis of geomaterial, in this case the porous rocks. in this study, which is a...

Thermo-hyperelastic problems at finite strains belong to a category of non-linear coupled problems that impose challenges on their numerical treatment. We present the weak-form for a 1-D coupled, stationary, thermo-hyperelastic system with constant or temperature-dependent material properties. The coupled system is discretized by a ‘monolithic’ high-order finite element method (p-FEM) based on ...

This work is concerned with the numerical solution of variational problems in elastoplasticity. Since the whole class of all possible elastoplastic problems is too large for a common treatment, we restrict ourselves to the investigation of problems which are quasi-static, and where strain and displacement are related linearly. Further, the homogeneous and isotropic material should obey the Pran...

A technique to identifY damping parameters directly from the frequency response functions (FRF) in matrix forms has been developed. Furtl1ermore, the technique identifies the viscous damping and structural damping coefficients separately. The technique provides more accurate damping values because it does not rely on the information of the natural modes as in the conventional method. The dampin...

This paper presents an object-oriented program system for finite element analysis implemented in Java. The main part is about concepts for the analysis of three-dimensional continua using the p-version of FEM. An object-oriented model for the related concepts of hierarchic basis functions and the blending function method is introduced. In order to improve the performance of the application, a h...

Limit-equilibrium method (LEM) and finite element method (FEM) with strength reduction method (SRM) techniques are the most widely used analysis tools in slope stability assessment. Recently, researchers have reported that both factor of safety (FOS) values and failure surfaces obtained from LEM and FEM are generally in good agreement, except in some particular cases. In this paper, the FOS and...

The online monitoring of induction motors is becoming increasingly important. The main difficulty in this task is the lack of an accurate analytical model to describe a faulty motor. A fuzzy logic approach may help to diagnose induction motor faults. This work presents a reliable method for the detection of stator winding faults (which make up 38% of induction motor failures) based on monitorin...

his paper investigates the influence of the rotor structure, more specifically, the influence of the open angle between the two magnet’s segments of each V-shape pole on the general characteristics of the machine keeping always the same magnets volume. In fact the investigation is done by using a free Finite Elements Methods (FEM) program coupled with another optimization program. This obtained...

The paper is devoted to the convergence analysis of a well-known cell-centered Finite Volume Method (FVM) for a convection-difïusion problem in R. This FVM is based on Voronoi boxes and exponential fitting. To prove the convergence of the FVM, we use a new nonconforming PetrovGalerkin Finite Element Method (FEM) for which the System of linear équations coïncides completely with that of the FVM....

Developing a high performance platform for large-scale, high-intensity data processing is a priority for researching cost-effective parallel finite element methods (FEM). This paper introduces an efficient MapReduce-MPI based strategy for parallel 3D finite element mesh processing, demonstrates the potential benefits of this approach for optimally utilizing system resources. Preliminary experim...
