Скачать или смотреть Mode I "Wing" Crack Propagation

The rise of new technologies such as hydrofracking and geothermal, and possible future technologies such as carbon sequestration, mean that energy industry scientists need a sophisticated understanding of how and why rocks crack deep beneath the earth, and how fluids efffect that process. One of several new videos made by our researchers for the Society of Exploration Geophysicists meeting, this work by Ekaterina Bolostkaya, a student of Prof. Hager in @MIT Department of Earth, Atmospheric and Planetary Sciences, models the propagation of a crack based on stress andf strain conditions. Ekaterina is this year's recipient of the Nafi Toksöz Fellowship, named for the founder of ERL.
