A three-dimensional Fe nonlinear analysis of membranes
Computers & Structures, 1996This paper presents a three-dimensional finite element method for computing stress and deformation of membrane structures. A conjugate pair of strain and stress tensors, the Green strain tensor and the Second Piola-Kirchhoff stress tensor are adopted to give the constitutive equation of Mooney material. By means of exploiting the plane stress condition

NONLINEAR FE ANALYSIS OF THE HYSTERESIS BEHAVIOR OF SMA
International Journal of Computational Engineering Science, 2001This paper presents a nonlinear finite element procedure for the simulation of the hysteresis behavior and the shape memory effect of shape memory alloy (SMA) materials. The consitutive equation is based on the consistent mathematical description of martensite fraction evolution during the thermoelastic phase transformation in shape memory alloys ...

FE analysis of continuous shear connector
IABSE Congress Reports, 2021<p>Composite bridges with encased steel beams, or nowadays, rather encased steel continuous shear connectors are a welcome option for short span railway or road bridges. With lower construction height and easy construction of prefabricated composite beams it brings a new, complex, solution for replacement of older, overserved bridges, as well as ...

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 ...

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 ...

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.

1993
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

Magnetic analysis of Fe dilute alloys
Journal of Alloys and Compounds, 1993Abstract Magnetic measurements disclosed that intermetallic compounds exist in the rapidly quenched La Fe system, where no compound has been reported in equilibrium. In as-quenched alloys of 1–8 at.% Fe, small ferromagnetic clusters are found to exhibit superparamagnetism, in the matrix of the f.c.c. β-La phase. Electron diffraction experiments

Mössbauer analysis of Fe−N austenites
Hyperfine Interactions, 1992Analysis of transmission Mossbauer spectra for high nitrogen Fe−N austenites is done in terms of five iron environments dealing with first and second nearest neighbour shells. The similar analysis for Fe−C austenites which displays only three iron environments led to the conclusion that carbon atoms are ordered whereas nitrogen atoms are more randomly ...

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.
