A model of damaged medium for evaluating the durability of structures subjected to combined low- and high-cycle fatigue loading

Abstract: В работе рассматриваются вопросы численного моделирования трансформации нелинейных поверхностных гравитационных волн в условиях мелководных заливов. Дискретная модель построена на основе нелинейных уравнений мелкой воды. Приведены граничные и начальные условия. Методом расщепления по физическим процессам получена система из трех уравнений. Определен порядок аппроксимации, исследованы условия устойчивости дискретной модели. Для решения системы уравнений использован метод прогонки. Представлены профили поверхнос… Show more

“…It is the case that experimentally supported and discussed in literature last time (see, e.g. [8][9][10] Let us discuss the physical picture of material behavior that is described by this model of the function ݂(ߛ). There is no expected the appearing of a fatigue crack in the interval ߛ ∈ [0,1].…”

“…Then, parameter ܾ * has the same physical meaning that it is in the model which is described by Eq. (9). Namely, it bound the minimal value of the "non-dangerous" part of the specific energy under the loading.…”
