Hydraulic fracturing in ice boreholes: Theory and tests
, 2019 Hydraulic fracturing is the well-known phenomenon that can occur intentionally, as it is used in the petroleum industry to stimulate the flow of natural gas or oil, or naturally, for example, as a reason for calving of ice shelves.

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Deep hybrid modeling of chemical process: Application to hydraulic fracturing
Computers and Chemical Engineering, 2020 Process modeling began with the use of first principles resulting in ‘white-box’ models which are complex but accurately explain the dynamics of the process. Recently, there has been tremendous interest towards data-based modeling as the resultant ‘black-
