    Description / Table of Contents: Übersicht Vorgestellt wird eine axialsymmetrische Spannungsanalyse mittels Reihen für einen transversalisotropen, kurzen Hohlzylinder unter einer äußeren Bandlast. Für die Analyse wird die verallgemeinerte Elliottsche Lösung benutzt. Die Lösung besteht aus fünf unabhängigen Potentialen, welche zwei Arten der Elastizitätslösung abgeben. Die Randbedingungen der Schubspannung auf den vier Flächen werden genau erfüllt. Die anderen Randbedingungen werden durch eine Fouriersche Reihenentwicklung oder eine Fourier-Besselsche Reihenentwicklung numerisch erfüllt. Die numerischen Resultate der Spannungen in einem Magnesiumkristall und einem Kadmiumkristall als Beispiele transversal-isotroper Materialien und in einem isotropen Material werden illustriert. Der Einfluß der Anisotropie auf die Spannungen wird durch Vergleich mit den Spannungen im isotropen Material untersucht.
    Notes: Summary An axi-symmetric stress analysis of a transversely isotropic, short hollow cylinder subjected to an outer band load is presented in a series form. The generalized Elliott's solution is used for the analysis. The solution consists of five independent potential functions which yield two kinds of elasticity solution. The boundary conditions for the shearing stress on the four surfaces are exactly satisfied. Other boundary conditions are numerically satisfied with the aid of a Fourier series expansion or a Fourier-Bessel series expansion. Numerical results for stresses in magnesium and cadmium crystals, as examples of transversely isotropic materials, and in an isotropic material are illustrated. The effect of anisotropy on the stresses is investigated by comparison with the stresses in the isotropic material.

    Description / Table of Contents: Übersicht Vorgeschlagen wird ein neues, allgemeines Verfahren zur Lösung transienter thermoelastischer Probleme transversal-isotroper Körper in kartesischen Koordinaten. Das Lösungsverfahren besteht aus fünf Fundamentallösungen und kann unter Berücksichtigung der Beziehungen zwischen den Materialkonstanten der Transversal-Isotropie in fünf Gruppen eingeteilt werden Eine Gruppe entspricht dem Goodierschen thermoelastischen Potential bzw. der verallgemeinerten Boussinesq-Lösung und der Mitchell-Funktion. Als Anwendung dieses Lösungsverfahrens wird ein inverses transient thermoelastisches Problem des transversal-isotropen, unendlichen Halbraumes untersucht.
    Notes: Summary In the present paper we propose a new general solution technique for transient thermoelastic problems of transversely isotropic solids in Cartesian coordinates. The solution technique consists of five fundamental solutions. By considering the relations among the material constants of transverse isotropy, the solution technique is classified into five groups. One among those corresponds to Goodier's thermoelastic potential function as well as the generalized Boussinesq solutions and the Michell function. For an application of the solution technique, an inverse problem of transient thermoelasticity in a transversely isotropic semi-infinite solid is analyzed.

    Notes: Summary The bending of a thick rectangular plate with all the edges completely clamped is analyzed by the three-dimensional theory of elasticity. A partially distributed uniform load over the top face is dealt within the analysis. The boundary conditions of the completely clamped edges are prescribed by three-dimensional, exact conditions that three displacement components vanish at the faces. The stress distributions at the edges are minutely examined by making the best use of advantages of the exact analysis. The stress distributions for the case of a fully distributed uniform load are compared with those obtained by Reissner's theory. The values of deflections and internal forces for various thickness-length ratios are also presented.

    Notes: Summary Goodier has proposed the thermoelastic potential function in order to analyze thermoelastic problems for isotropic solids. The thermoelastic problem can be reduced to the elastic problem by his technique. Elastic problems are in general analyzed by the generalized Boussinesq solutions and the Michell function. This paper discusses a new solution technique for thermoelastic problems of transversely isotropic solids in cylindrical coordinates. The present solution technique consists of five fundamental solutions which are developed from the Goodier's thermoelastic potential function, the generalized Boussinesq solutions and the Michell function. Considering the relations among the material constants of transverse isotropy, the present solution technique can be classified into two cases. One of them can be reduced to the three solution techniques above which are specifically for isotropic solids only. As an application of the present solution technique, a transient thermoelastic problem in a transversely isotropic cylinder with an external crack is analyzed.
