Finite element methods are applied to many different branches of engineering, including structural analysis, heat transfer, fluid flow, electromagnetics, mold analysis. Therefore the use of FEA needs to be guided by theoretical principles of the particular discipline, notwithstanding the computing power of the hardware. This chapter is a cursory review

Quantitative AES analysis of Fe-Cr and Fe-Ni-Cr alloys
Applications of Surface Science, 1983Abstract Conventional, derivative mode AES, in combination with Ar + sputtering, was applied to a wide range of commercial Fe-Cr and Fe-Ni-Cr alloys. The roles played by matrix effects, sputtering phenomena, peak interference, peak height variation and poor vacuum backpressure in obtaining quantitative analyses were studied.

A thermodynamic analysis of the Fe−C and Fe−N phase diagrams
Metallurgical Transactions A, 1979The experimental information on the Fe−C and Fe−N phase diagrams are evaluated in order to be able to recalculate the phase diagrams in close agreement with the experimental information available. Analytical expressions for the Gibbs energy of pure iron in the bcc and liquid states relative to the fcc state have been obtained by means of power series ...

Diffraction analysis of α-Fe precipitates in a polycrystalline Cu–Fe alloy
Materials Characterization, 2015Abstract The microstructure and orientation of α-Fe precipitates after a small amount of deformation in a polycrystalline Cu–2.1 wt.% Fe alloy were investigated. Analysis of electron diffraction patterns and Moire fringes of α-Fe precipitates showed that the orientation relationship between α-Fe precipitates and Cu matrix was close to Pitsch ...

Automated FE analysis of flange assemblies
Sealing Technology, 1996Abstract An automated finite element computer program to analyse bolted circular weld neck flange and gasket assemblies has been developed. The program is based on an extensive database of British, European and American flange and gasket standards. The program is ideal for identifying problem areas and conducting sensitivity studies.

Notch-Stress Analysis by FE Submodeling
Journal of Pressure Vessel Technology, 1997This paper presents experiences in detailed finite element analyses of pressure vessel components with respect to load-carrying capacity and fatigue strength. The application of the submodeling technique for shell-to-solid models is discussed.

FE transient analysis of the magnetostrictive actuator
International Journal of Applied Electromagnetics and Mechanics, 2016The paper deals with a magnetostrictive fast-acting actuator applied as a driving device for plasma valve designed for so called ``high intensity plasma pulses gun''. The actuator is characterized by a small displacement, but with a very short response time - below 0.1 ms.

FE Analysis for Different Supports
2009In Chapter 4 we became acquainted with various edge conditions in thin plate theory; in Chapter 5 we applied this knowledge to square plates with three different support conditions. Here we meet the three cases again, now they appear in a FE analysis. In Chapter 5 we considered a two-way sine load and a homogeneous distributed load.

CEMS analysis of Fe thin films
Hyperfine Interactions, 1990The application of the Conversion Electron Mossbauer Spectroscopy (CEMS) to the structural and magnetic analysis of ultrathin films and their interfaces is reported. Fe(110) films were deposited on W(110) under UHV conditions and analyzed in situ using CEMS.

Analysis of nitrogen solubility in austenitic Fe-Cr and Fe-Ni alloys
Scripta Metallurgica et Materialia, 1990An evaluation of nitrogen solubility data from previous studies in the binary Fe-Cr and Fe-Ni systems was performed. When these data were treated and cast into log f N vs % X (X=Cr, Ni) plots, they revealed that the isothermal nitrogen contents of several Fe-Cr alloys at 101 kPa nitrogen pressure increase with rising chromium level, but, at a given ...
