Width of adiabatic shear bands [PDF]
Materials Science and Technology, 1985 AbstractAn equation for the half-width of an adiabatic shear band is derived. With reference to the equation, the importance of thermal conductivity, temperature, and viscosity in determining the bandwidth are illustrated. It is shown that calculations of shear band width are fairly close approximations to those obtained experimentally.

On the persistence of adiabatic shear bands [PDF]
EPJ Web of Conferences, 2012 It is generally agreed that the initiation and development of adiabatic shear bands (ASBs) are manifestations of damage in metallic materials subjected to high strain rates and large strains as those due to impact in a Hopkinson Bar system. Models for evolution of these bands have been described in the literature.

Propagation of Adiabatic Shear Bands [PDF]
Le Journal de Physique IV, 1997 The dynamic propagation of a shear band is assessed in mode II. A layer of finite thickness is subjected to siinple shearing. The band propagates in the shear direction under steady state conditions. A variational approach is developed to calculate the shear band velocity and the length of the process zone.

The genesis of adiabatic shear bands
Scientific Reports, 2016 AbstractAdiabatic shear banding (ASB) is a unique dynamic failure mechanism that results in an unpredicted catastrophic failure due to a concentrated shear deformation mode. It is universally considered as a material or structural instability and as such, ASB is hardly controllable or predictable to some extent.

Major Steps in the Discovery of Adiabatic Shear Bands [PDF]
Metallurgical and Materials Transactions A, 2015 The ASB phenomenon was first described by Russian researchers in 1928 and 1935. Translations of both papers are included.

ADIABATIC SHEAR BAND VELOCITIES
Le Journal de Physique Colloques, 1985 A new method of investigating adiabatic shear band velocities under hydrodynamic pressure is described. Interpretation of propagation rates depends on an appreciation of the stress and strain fields into which propagation occurs. The C-HEMP computer code has been used to characterize load histories, and results are described for comparison with the ...

Numerical Simulation of Adiabatic Shear-Band Formation in Composites
Automatic Control and Computer Sciences, 2016 The process of plastic flow localization under shear deformations of a composite material consisting from welded steel and copper is studied. A mathematical model describing this physical process is proposed. A new numerical approach based on Courant–Isaacson–Rees scheme is suggested.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing
Advanced Science, EarlyView.Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...
