Thermal Drilling

This paper presents a numerical study on thermal jet drilling of granite rock that is based on a thermal spallation phenomenon. For this end, a numerical method based on finite elements and a damage–viscoplasticity model are developed for solving the underlying coupled thermo-mechanical problem. An explicit time-stepping scheme is applied in solving the global problem, which in the present case is amenable to extreme mass scaling. Rock heterogeneity is accounted for as random clusters of finite elements representing rock constituent minerals. The numerical approach is validated based on experiments on thermal shock weakening effect of granite in a dynamic Brazilian disc test. The validated model is applied in three-dimensional simulations of thermal jet drilling with a short duration (0.2 s) and high intensity (approx. 3 MW m −2 ) thermal flux. The present numerical approach predicts the spalling as highly (tensile) damaged rock. Finally, it was shown that thermal drilling exploiting heating-forced cooling cycles is a viable method when drilling in hot rock mass. This article is part of the theme issue ‘Fracture dynamics of solid materials: from particles to the globe’.

Do So

Abstract An important step in teaching critical reading for online civic reasoning is building teachers’ own acceptance of and comfort with screen literacies, understanding them not as alternative to gold-standard book literacies but as normative. To do so, teachers must better understand how web-based texts, and the reading of them, differ from the “classical” critical reading most teachers are used to. This article examines the “quantum” nature of web-based texts—their fundamental instability, their reader constructedness, and their nature as processes rather than objects—and relates these features to hyper-reading and other reading strategies that research shows allow engaged readers to screen-read critically.
