Published in 2017 at "Journal of Petroleum Science and Engineering"

DOI: 10.1016/j.petrol.2017.07.052

Abstract: Abstract Drilling in complex geological settings often possesses significant risk for unplanned events that could potentially impede already cost-demanding operations. Lost circulation, a major challenge in well construction, refers to the loss of drilling fluid… read more here.

Published in 2019 at "Thin-Walled Structures"

DOI: 10.1016/j.tws.2019.02.008

Abstract: Abstract A simplification of Lame’s equation to determine radial and hoop stress due to interference on press-fits is introduced. The two novel simplified equations introduced in this paper provide a method to quickly and accurately… read more here.

Published in 2017 at "Superconductor Science and Technology"

DOI: 10.1088/1361-6668/aa76a2

Abstract: We have performed the numerical simulation of mechanical stresses (hoop stress, σ θ and radial stress, σ r) in REBaCuO ring bulks with an infinite and finite height reinforced by metal (aluminum alloy or stainless… read more here.
