| Автори: | Федак, Сергій Ігнатович Ясній, Петро Володимирович Гладьо, Володимир Богданович Шульган, Ігор Володимирович |
| Бібліографічний опис: | The paper proposes finite element model for studying of influence of brittle inclusions in the material on opening in the crack tip in the conditions of static and dynamic creep, when the parameters of structural heterogeneousness is taken into consideration. Using this model, there have been studied the influence of shape ratio and specific part of inclusions of heterogeneous material on the crack tip opening increase and material damage at static and dynamic creep. |
