    Notes: Abstract The computational complexity of a number of problems concerning induced structures in graphs is studied, and compared with the complexity of corresponding problems concerning non-induced structures. The effect on these problems of restricting the input to planar graphs is also considered. The principal results include: (1) Induced Maximum Matching and Induced Directed Path are NP-complete for planar graphs, (2) for every fixed graphH, InducedH-Minor Testing can be accomplished for planar graphs in time0(n), and (3) there are graphsH for which InducedH-Minor Testing is NP-complete for unrestricted input. Some useful structural theorems concerning induced minors are presented, including a bound on the treewidth of planar graphs that exclude a planar induced minor.

    Notes: Abstract The graphical method of solution given in the paper [1] is used to study a pair of dislocations with opposite signs of the Burgers vectors in the Frenkel model of a crystal. The dependence of the force between the dislocations on their mutual distance is determined.

    The concept of “incompatibility” for a simple model of a crystal lattice (1967)

    Details
    ISSN: 1572-9486
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract A system of equations is derived for a simple model of a crystal lattice disturbed by a dislocation. The model is represented by two rows of atoms. The system of equations is analogous to that describing a singular dislocation in the theory of the continuous distribution of crystal imperfections. The method of solving the derived system of equations is given.

    Notes: Abstract The stability of equilibrium configurations of atoms, which represent a dislocation, is studied on a one-dimensional static model of a crystal. The potentialW, which represents the influence of the surrounding crystal lattice on the atoms of the model, is composed of parabolic sections. An expression is derived for Peierls stress and cases are found when this stress is equal to zero.

    Notes: Abstract A graphical method is used to determine the static equilibrium configurations of atoms which correspond to a one-dimensional model of a crystal disturbed by a dislocation. The question of the number of equilibrium configurations and their stability with respect to a homogeneous stress is solved and cases of an anomally low Peierls stress are studied.

    Description / Table of Contents: Abstract В статье выведены соотношения для поля упругого напряжения вокруг линейной дислокации в неорганиченном анизотропном пространстве. Среда, окружающая ядро дислокации, вырезана в форме эллиптического цилиндра, поверхность которого свободна. В качестве примера приводится расчет поля вокруг трещины в кристалле, модель которой предложил в работе [9] Фуйта.
    Notes: Abstract Relations are derived for the elastic stress field around a linear dislocation in an infinite medium with general anisotropy. The strongly deformed material around the core of the dislocation is cut out in the shape of an elliptic cylinder. The conditions of a free surface are used on the boundary thus formed. The calculation of the field around a crack in a crystal, the model of which was proposed by Fujita in [9], is given as an example.

    Low cycle fatigue cracking of Al 20wt% Zn multicrystals (1987)
    Springer
    Czechoslovak journal of physics 37 (1987), S. 619-624 
    Details

    Topics: Physics
    Notes: Abstract Low cycle fatigue data are reported for multicrystalline specimens (i.e. polycrystals with a few large grains in the gauge section) of age-hardened AlZn alloy with elliptical G. P. zones. Experiments were carried out at constant strain amplitude, room temperature and frequency 2 Hz. The discussion focused on the role and relative importance of grain boundaries, extrusions and coarse slip bands for crack nucleation and propagation. Precipitation free zones bordering the grain boundaries are the most favoured sites of crack nucleation and early crack growth. The prevailing mechanism of the initial stage of transcrystalline cracking is alternating slip or shear. The large cracks with an extended plastic zone tend to follow the extrusions which are formed at the crack tip after sufficients number of cycles.
