CEMS analysis of Fe thin films

Hyperfine Interactions, 1990
The 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.

Magnetic analysis of Fe dilute alloys

Journal of Alloys and Compounds, 1993
Abstract 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, 1992
Analysis 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 ...

Notch-Stress Analysis by FE Submodeling

Journal of Pressure Vessel Technology, 1997
This 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.

Guidelines for FE Analysis

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

FE Analysis of FRP Pressure Vessel

Key Engineering Materials, 2019
In this paper the main focus is on analyzing the effect of various parameters like winding angle, winding pattern and fiber volume fraction on the stresses generation in a composite pressure vessel using Finite Element (FE) approach. The present study makes use of three different composite materials namely GFRP (Glass Fiber Reinforced Plastic), CFRP ...

Nonlinear FE Analysis of RC Beams

2001
ABSTRACT A moment-curvature relationship to simulate the behavior of reinforced concrete beam under cyclic loading is introduced. Unlike previous moment-curvature models and the layered section approach, the proposed model takes into consideration the bond-slip effect by using monotonic moment-curvature relationship constructed on the basis of the ...

A three-dimensional Fe nonlinear analysis of membranes

Computers & Structures, 1996
This 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

FE Analysis for Different Supports

2009
In 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.

FE analysis of a low-frequency microstrip antenna

IEEE Transactions on Magnetics, 2002
The design and the finite-element analysis of a novel microstrip antenna suitable for low-frequency applications is presented. The patch is mounted on a double-layered substrate of ferroelectric and ferrimagnetic materials to lower the resonant frequencies.
