The use of the Finite Element Method (FE) is an appropriate way to study occlusal forces and tooth movement. The purpose of this study was to evaluate the effects of different occlusal contact patterns on tooth displacement in an adult dentition using a three-dimensional FE model of a human maxilla and mandible. Initially, images of a computerized tomography scan were redrawn in a computer prog...

Abstract It is widely known that the triangle finest geometric unit, and therefore applying triangulation joint to rock mass simulation can not only accurately describe fracture morphology of engineering, but also inversely deduce mechanical parameters blocks joints. Based on soil two-dimensional analysis program (RS2), this paper compiles a with MATLAB realizes parameterized setting network (T...

introduction: because of the importance of vertebral compressive fracture (vcf) role in increasing the patients’ death rate and reducing their quality of life, many studies have been conducted for a noninvasive prediction of vertebral compressive strength based on bone mineral density (bmd) determination and recently finite element analysis. in this study, qct-voxel based nonlinear finite eleme...

In this paper, a time stepping 2D and 3D FEM is performed for modeling and analysis external rotor DFIG .The finite element method currently represents the state-of-the-art in the numerical magnetic field computation relating to electrical machines. FEM is a numerical method to solve the partial differential equations (PDE) that expresses the physical quantities of interest, in this case Maxwel...

The Switched Reluctance Machine (SRM) is ideal for safety critical applications (aerospace, automotive, defense, medical, etc.) where it is desirable that the electrical drive system to be fault tolerant. During the design of a fault tolerant electrical drive system it is indispensable to use advanced simulation techniques. Finite elements method (FEM) based magnetic field computation programs ...

This paper presents research on a non-symmetric damage element developed initially for the Ularc Finite Element Method (FEM) program. The paper outlines the mathematical development of the beam element, provides details of the use of the damage model in the FEM implementation, and sets out the limitations of the method. Recent mathematical research has focussed on implementing a symmetric finit...

The present paper refers to some examples that use the finite element method (FEM) in the process of analysis, design and optimization of the permanent magnet (PM) generators used in wind applications. The 2D-FEM program Opera 13 of Vector Fields is used in the analyzed examples. These examples refer to two types of radial flux low speed PM generators of 5 KW for wind applications. Some possibi...

Methods A Finite Element Method (FEM) model is used to simulate industrial forming processes such as bending and deepdrawing. The model consists of multiple polymer and metal layers. The simulations are performed using the FEM programMARC, which is coupled to an external program. The coupling is required for the meshing of the model and other features. Results Bending and deep-draw simulations ...
