    ASSUMED STRESS C0 QUADRILATERAL/TRIANGULAR PLATE ELEMENTS BY INTERRELATED EDGE DISPLACEMENTS (1996)
    Chichester [u.a.] : Wiley-Blackwell
    International Journal for Numerical Methods in Engineering 39 (1996), S. 1041-1051

    ISSN: 0029-5981

    Notes: This paper presents two simple quadrilateral C0 plate bending elements with explicit element stiffness matrix. The element formulation is based on assumed element stress fields and the interrelated transverse displacement and rotation along element boundaries. The interrelated edge displacements not only can result in higher-order displacements interpolations for higher accuracy element and overcome the shear locking in thin plate analysis encountered by C0 plate elements, but can also unify the four-noded quadrilateral element and its corresponding three-noded triangular element. The latter cannot be achieved by the assumed displacement formulation. The numerical examples demonstrate the accuracy and robustness of the present assumed stress C0 plate elements.

    Linear and angular effects on the 1H and 13C NMR spectra of tricyclic aromatic ketones formally derived from tetralone (1989)
    Chichester : Wiley-Blackwell
    Organic Magnetic Resonance 27 (1989), S. 606-607 
    Details
    ISSN: 0749-1581
    Keywords: 13C NMR ; 1H NMR ; Tricyclic aromatic ketones ; Linear and angular effects ; Chemistry ; Analytical Chemistry and Spectroscopy
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: Complete unambiguous assignments of 1H and 13C chemical shifts for α-tetralone, a related dihydroanthracenone and two related dihydrophenanthrones are presented. Data are based on results of 400 MHz 1H-1H and 1H-13C COSY experiments, and permit an evaluation of linear vs. angular endo and exo ketone orientation on the NMR parameters.
