  • xrd microstructural analysis of mullites obtained from kaolinite alumina mixtures
    Journal of The European Ceramic Society, 2000
    Co-Authors: Miguel A. Sainz, Jaume Bastida, F. J. Serrano, Jose Manuel Amigo, A Caballero
    Abstract:

    Abstract A microstructural study of mullite obtained by the reaction sintering of kaolinite–α–alumina mixtures in the range 1150–1700°C has been performed by using X-ray line profile analyses together with scanning and transmission electron microscopy equipped with microanalysis by energy dispersion (Sem-EDS, TEM-AEM). Two kinds of morphology corresponding to primary (elongated grains) and secondary (equiaxed grains) mullite have been observed. A bimodal crystallite size distribution has been detected through XRD microstructural analysis from 1300°C. The results obtained by this method are compared with Sem/TEM data.

  • Nonlinear eigenvalue analysis for spectral element method
    Computers & Structures, 2021
    Co-Authors: Avisek Mukherjee, Soumyadipta Sarkar, Arnab Banerjee
    Abstract:

    Abstract Spectral element method (Sem) is a robust and efficient mathematical technique for dynamic analysis of structures in frequency domain. Unlike finite element method (FEM), in Sem, the dynamic stiffness matrix forms a nonlinear eigenvalue problem (NLEP) to compute the natural frequencies and vibration modes of the structure which cannot be solved using linear numerical eigen-solvers. In this paper, two distinct numerical methods, i.e. (1) a root finding method of rational polynomial functions and (2) a linearization of Lagrange matrix interpolating polynomials, have been used to compute the eigenvalues of a problem more efficiently employing Sem. These proposed methods can solve NLEP in a stable, efficient and accurate way even in the presence of singularities. The accuracy of these methods are numerically evaluated by comparing with the solutions from the modal analysis using FEM.

  • Electron Microscopy in Polymer Science
    Applied Spectroscopy Reviews, 1993
    Co-Authors: Goerg H. Michler
    Abstract:

    Abstract In many fields of research in science, engineering, and medicine, electron microscopy as a method for directly imaging submicroscopic structures has become increasingly important in recent decades. Electron microscopy (EM) includes several different techniques: conventional transmission electron microscopy (TEM), high-resolution electron microscopy (HREM), highvoltage electron microscopy (HVEM), scanning electron microscopy (Sem), analytical electron microscopy (AEM), emission electron microscopy (EEM), and others. In the past the central aim of using electron microscopy was structure determination, but recently it has been of growing importance for also investigating different processes, i.e., changes in materials by interaction with several influential factors (e.g., heat, electric or mechanic fields, mechanical loading). Of particular interest is the study of the micromechanical processes of deformation and fracture. Therefore, electron microscopy is a very powerful tool for materials science....
