    EFFECT OF MECHANICAL PROPERTIES OF THIN STRIPON STABILITY WHEN DRESSING STRETCHING

    K.S. Remnev

    The influence of the mechanical properties of thin strip on the stability when editing tension with small extensions is revealed.

    Key words: mechanical properties, anisotropy, edit, expand, voltage, strain stability.

    Remnev Kirill Sergeevich, candidate of technical sciences, docent, mpf-tula@rambler.ru, Russia, Tula, Tula State University
