High‐Pressure Elasticity of CAS Phase and Its Implications for the Fate of Subducted Anorthosite Crust

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The CAS phase (CaAl4Si2O11) is a key phase formed in subducted silica‐alumina rich crustal and sedimentary materials under the mantle transition zone conditions. In this study, its elastic properties were investigated using first‐principles calculations up to 30 GPa.

Representation of Stratocumulus and Shallow Cumulus Cloud Fraction Near the Southeast Pacific Ocean ITCZ in ERA5 and MERRA‐2 Reanalyses

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 10, 28 May 2026.
Abstract Model precipitation biases in the intertropical convergence zone (ITCZ) are often tied to the underestimation of stratocumulus (Sc) and shallow cumulus (Cu) clouds. We design a method to distinguish between Sc and Cu cloud regimes under subsidence on daily timescales based on cloud top pressure and vertical velocity to investigate the spatial ...

Experiment of the Formation of Adiabatic Shear band in Sheet Metal

open access: yes, 2000
The adiabatic shear band formation is one of the high speed deformation phenomena, in which adiabatic shear failure is physically observed as a narrow band of the continuous shear strain.

Adiabatic shear band formation as a result of cryogenic CNC machining of elastomers

open access: yes, 2011
The traditional method for producing polymer-based products is the use of moulding technologies such as injection moulding. CNC machining methods are predominantly used for metal part manufacture. The use of CNC machining methods for direct machining of

Meteorite impact shatter cones – adiabatic shear bands?

open access: yes, 2009
Shatter cones are distinctive, striated, conical fractures found in shocked rocks at meteorite impact structures. They are estimated to form at shock pressures from 2 to 25 GPa and range in size from a few millimeters up to more than 10 meters in length.

Critical adiabatic shear strength of low alloy steel under compressive loading

open access: yes, 2022
S.657-674The adiabatic shear band phenomenon is investigated by means of a Split-Hopkinson-Pressure bar with dies, which produce a shear loading in the specimen.

Adiabatic shear localization: occurrence, theories, and applications

open access: yes, 1992
Adiabatic shear localization is a mode of failure that occurs in dynamic loading. It is characterized by thermal softening occurring over a very narrow region of a material and is usually a precursor to ductile fracture and catastrophic failure.
