    Description / Table of Contents: Übersicht Es werden einige Klassen diskreter Strukturmodelle und stückweise linearer Fließ- und Verfestigungsregeln betrachtet. Dabei wird die elasto-plastische Reaktion eines Bauteiles auf eine vorgegebene Belastung durch schnell veränderliche Lasten sowie aufgeprägte Verzerrungen oder Verschiebungen mit Hilfe einer geeigneten Matrizen-Darstellung untersucht. „Inadaptation” bedeutet, daß die plastische Verformungsarbeit und folglich auch einige plastische Deformationen mit der Zeit unbegrenzt anwachsen, so daß kein Abfangen bei endlichen Verformungen („adaptation”) stattfindet. Es werden notwendige und hinreichende Bedingungen für ein derartiges Verhalten aufgestellt und in einem Satz formuliert, der als eine Verallgemeinerung des zweiten (des Koiterschen) Satzes der klassischen Plastizitätstheorie aufgefaßt werden kann.
    Notes: Summary Some broad classes of discrete structural models and piecewise linear yield loci and hardening rules are considered. The dynamic elastoplastic response to a given history of rapidly variable loads and imposed strains and displacements (“dislocations”) is studied on the basis of a suitable matrix description. Inadaptation means that the plastic work and, hence, some plastic deformations increase unlimitedly in time, i.e. the structure does not shakedown. Sufficient and necessary conditions for this occurrence are established and formulated in a theorem, which represents the extension to the dynamic range and to work-hardening structures of the second (Koiter's) shakedown theorem of classical plasticity.

    Notes: Abstract The critical magnetic scattering of neutrons by nickel was studied as a function of temperature and of the scattering vector κ in the range 0.008−0.04 Å−1 for various specimens ranging from a single crystal to heavily deformed polycrystals. The shift of the temperature where the maximum of the scattered intensity is found as a function of scattering vector κ depends on the degree of crystalline imperfection. For the single crystal the observed shift is ΔT/T≲ 5 · 10−3. On the basis of the Ornstein-Zernike theory the observed scattering by the single crystal yields the critical index $$\gamma = 2v = 1.32 \pm _{0.14}^{0.20} $$ as predicted by most of the theories.

    Notes: Plane stress structures of any shape and boundary conditions are simulated by finite element models with homogeneous stress and strain fields in each element. Besides the given live loads, dead loads (such as self-weight) depending on the unknown thickness distribution are allowed for. Possible practical requirements on geometry (minimum thickness, areas of equal thickness, areas of thickness variation in a prescribed way) are taken into account. Yield surfaces of the materials are piecewise linearized. On this basis the minimum weight design problem is formulated in terms of a linear program. This program is dualized and the pair of dual programming problems is discussed. The mechanical interpretation leads to the generalization of some known limit design theory results.Some numerical examples are given at the end.
