The thermoelastic problem for an infinite multiply connected anisotropic plate with holes and cracks in a linear heat flow is solved. The stress distribution and the stress intensity factors on heat-insulated boundaries are analyzed numericallyThe thermostressed state of isotropic plates with holes and cracks was analyzed in [7,10]. In the anisotropic case, such studies were conducted for plates with holes [8,9], with either concentrated heat sources or predefined peripheral temperature. No problems were solved for anisotropic plates with cracks or with holes and cracks, let alone heat flows. Three-dimensional stress problems for elastic and magnetoelastic bodies with cracks and inclusions are addressed in [13][14][15][16].The present paper sets forth a method for thermostress analysis of anisotropic plates with an arbitrary number, arrangement, and combination of holes and cracks under various thermal actions. Numerical results for plates with holes with heat-insulated boundaries in a linear heat flow acting at infinity will be presented.
У роботі досліджено проблему DoS / DDoS атак на навчальні ресурси зі сторони студентів. Сформульовано причини, що можуть спонукати студентів до здійснення кібератак на ЗВО або навчальні ресурси. Розглянуто приклад реальної DoS атаки автоматизованої системи контролю знань студентом, та способи виявлення особи кіберхулігана. Запропоновано певні заходи з упередження та протидії атакам.
