Finite Element Modeling of Drillstrings [PDF]
Mathematical and Computational Applications, 1996 A finite element model is presented for investigating dynamic behavior of drillstrings used in oil and gas wells. A Timoshenko beam element is used to model axial and transverse vibrations. The effect of axial load, gravity, the constraints due to stabilizers are considered.

Model Residual Stress by Finite Element Method
ITM Web of Conferences, 2018 This paper presents an original model developed by finite element method to simulate the behavior of the material to the method “Blind Hole Drilling”, to determine the residual stress. Modeling of this method is possible through the use of the “Birth and

Finite-Element Modelling of Biotransistors [PDF]
Nanoscale Research Letters, 2010 Current research efforts in biosensor design attempt to integrate biochemical assays with semiconductor substrates and microfluidic assemblies to realize fully integrated lab-on-chip devices. The DNA biotransistor (BioFET) is an example of such a device.

A finite element model of skin deformation. III. The finite element model [PDF]
The Laryngoscope, 1986 AbstractSkin flap design has traditionally been based on geometric models which ignore the elastic properties of skin and its subcutaneous attachments. This study reviews the theoretical and experimental mechanics of skin and soft tissues (I) and proposes a mathematical model of skin deformation based on the finite element method (III).

Co-Simulation of an Inverter Fed Permanent Magnet Synchronous Machine
Electrical, Control and Communication Engineering, 2014 Co-simulation is a method which makes it possible to study the electric machine and its drive at once, as one system. By taking into account the actual inverter voltage waveforms in a finite element model instead of using only the fundamental, we are ...

Development of frame finite element model for truss structures with semi-rigid connections
Engineering and Applied Science Research, 2018 The problem of connecting truss structures is one of the major concerns in structural analysis and design. The behavior of truss structures is usually analyzed using a common finite element model, which considers each member as a two-force member.

An interactive graphics system to facilitate finite element structural analysis [PDF]
, 1973 The characteristics of an interactive graphics systems to facilitate the finite element method of structural analysis are described. The finite element model analysis consists of three phases: (1) preprocessing (model generation), (2) problem solution ...

Finite element exterior calculus for parabolic problems [PDF]
, 2012 In this paper, we consider the extension of the finite element exterior calculus from elliptic problems, in which the Hodge Laplacian is an appropriate model problem, to parabolic problems, for which we take the Hodge heat equation as our model problem ...
