On the mechanics of chip formation in Ti-6Al-4V turning with spindle speed variation [PDF]

open access: yes, 2014
"In order to enhance material removal rate (MRR), a strategy that relies on higher depths of cut could be chosen if vibrational issues due to regenerative chatter did not occur.

The Arctic Coastal Erosion Model: Overview, Developments, and Calibration at Drew Point, Alaska

open access: yesJournal of Advances in Modeling Earth Systems, Volume 18, Issue 3, March 2026.
Abstract Permafrost coastlines are experiencing significant erosion as polar amplification has enhanced the effects of climate change in the Arctic. Warmer temperatures are increasing thermo‐denudation and more energetic oceans are increasing thermo‐abrasion in unlithified, ice‐bonded permafrost coastlines which comprise at least 40% of the circum ...

The Messinian Salinity Crisis Between Italy and Albania: The Peri‐Adriatic Depression and Southern Adriatic Basin Records

open access: yesBasin Research, Volume 38, Issue 2, March/April 2026.
Basin‐scale correlation of Messinian salinity crisis (MSC) deposits across the Apennine–Albanide foreland basin system integrating outcrop and subsurface data. ABSTRACT We reconstructed the geological evolution of the Albanides during the Messinian salinity crisis (MSC), based on the integration of outcrop and subsurface data from both onshore (peri ...

FEM-based prediction of workpiece transient temperature distribution and deformations during milling [PDF]

open access: yes, 2018
In high-speed dry milling of thin-walled parts, the cutter-workpiece temperature rises asymptotically with cutting speed, causing excessive cutter tooth wear and workpiece thermal expansion, which in turn reduces the cutter life and produces dimensional ...
