wind farm impact on generation adequacy in power systems
در سال های اخیر به دلیل افزایش دمای متوسط کره زمین، بشر به دنبال روش های جایگزین برای تامین توان الکتریکی مورد نیاز خود بوده و همچنین در اکثر نقاط جهان سوزاندن سوخت های فسیلی در نیروگاه های حرارتی به عنوان مهم ترین روش تولید توان الکتریکی مطرح بوده است. به دلیل توجه به مسایل زیست محیطی، استفاده از منابع انرژی تجدید پذیر در سال های اخیر شدت یافته است. نیروگاه های بادی به عنوان یک منبع تولید توان...
15 صفحه اولCrack initiation in brittle materials
In this paper we study the crack initiation in a hyper-elastic body governed by a Griffith’s type energy. We prove that, during a load process through a time dependent boundary datum of the type t → tg(x) and in absence of strong singularities (this is the case of homogeneous isotropic materials) the crack initiation is brutal, i.e., a big crack appears after a positive time ti > 0. On the cont...
متن کاملThermal activation of rupture and slow crack growth in a model of homogenous brittle materials
– Slow crack growth in a model of homogenous brittle elastic material is described as a thermal activation process where stress fluctuations allow to overcome a breaking threshold through a series of irreversible steps. We study the case of a single crack in a flat sheet for which analytical predictions can be made, and compare them with results from the equivalent problem of a 2D spring networ...
متن کاملThe Breaking of Brittle Materials
A long metal thread breaks more easily than a short one—an observation Leonardo da Vinci made in the 15th century. It all comes down to simple statistics: the larger an object, the more likely it is to contain a region that breaks when subject to stress. The fracture properties of brittle materials also depend on the disorder in their underlying structure: a homogeneous material like glass brea...
