This paper reports the development of finite element software for creep damage analysis. Creep damage deformation and failure of high temperature structure is a serious problem for power generation and it is even more technically demanding under the current increasing demand of power and economic and sustainability pressure. This paper primarily consists of three parts: 1) the need and the just...

Object composition offers significant advantages over class inheritance to develop a flexible software architecture for finiteelement analysis. Using this approach, separate classes encapsulate fundamental finite-element algorithms and interoperate to form and solve the governing nonlinear equations. Communication between objects in the analysis composition is established using software design ...

a non-linear finite element model could be a useful tool in the development of a method of predicting soil pressure-sinkage behaviour, and can be used to investigate and analyze soil compaction. this study was undertaken to emphasize that the finite element method (fem) is a proper technique to model soil pressure-sinkage behaviour. for this purpose, the finite element method was used to model ...

This paper presents the application of finite element method (FEM) to analyze the tube temperature distribution in a water tube boiler. Two-dimensional (2-D) finite element models are developed where the axi-symmetric triangular elements for the cross section area along the water tube are applied in computer software namely MSC Patran-Nastran. The analysis of the temperature distribution for ev...

Goal oriented error estimation and adaptive procedures are essential for the accurate and efficient evaluation of numerical simulations that involve complex domains. By locally improving the approximation quality we can solve expensive problems which could result intractable otherwise. Here, we present an error estimation technique for enriched finite element approximations that is based on an ...

Chakraverty * Department of Mathematics, National Institute of Technology, Rourkela, Odisha -769008, India Abstract: Scattering of neutron collision inside a reactor depends upon geometry of the reactor, diffusion coefficient and absorption coefficien...

In the current research work, the problem of fracture mechanics in a plate with a central hole under tensile loading is studied. The stress intensity factors are calculated for a finite plate containing two symmetrical hole-edge cracks. The problem is solved by two different methods, namely the finite element method and the FRANC software analysis. At first the finite element method is used and...

This paper presents a new technique for development of tensegrity structures and their deployment in field, in two different modes strut based and cable based. A prototype module based on a half-cuboctahedron configuration is fabricated using commercially available materials. A new method of deployment is introduced for easy assembling and dismantling in field. The proposed structure and the as...

The present paper describes the development of a finite element based tool at the launcher directorate of the French Space Agency (CNES) in order to support the ground study and testing of fairing separation systems. The main topic is the finite element modeling process and its validation. The considered finite element methods and resolution algorithms are presented, with a focus on shell eleme...

In this study, callus formation strengths of the rat femurs are examined after bone fracture healing using the computer aided finite element methods. The rat femurs are modeled using computed tomography (CT) images using both MIMICS R12 and GEOMAGIC software for finite element applications for which ANSYS Workbench is employed. The mechanical properties of rat femurs are obtained using the thre...
