Rate dependent shear bands in a shear transformation zone model of amorphous solids [PDF]
, 2008 We use Shear Transformation Zone (STZ) theory to develop a deformation map for amorphous solids as a function of the imposed shear rate and initial material preparation.

Study of the Shear Strain and Shear Strain Rate Progression During Titanium Machining [PDF]
Journal of Manufacturing Science and Engineering, 2018 Machining is among the most versatile material removal processes in the manufacturing industry. To better optimize the machining process, the knowledge of shear strains and shear strain rates within the primary shear zone (PSZ) during chip formation has been of great interest.

Yield strain in shear banding amorphous solids [PDF]
Physical Review E, 2013 In recent research it was found that the fundamental shear-localizing instability of amorphous solids under external strain, which eventually results in a shear band and failure, consists of a highly correlated array of Eshelby quadrupoles all having the same orientation and some density $ $. In this paper we calculate analytically the energy $E( , )

The Influence of Shear Strain on the Torsion Capacity of Hybrid Beams [PDF]
Engineering and Technology Journal, 2020 This research discusses experimentally the shear strain of the reinforcement concrete hybrid beams composed of reactive powder concrete (RPC) at the peripheral and conventional concrete (CC) at the core beams under torsional strength tests.

Localization in inelastic rate dependent shearing deformations
, 2016 Metals deformed at high strain rates can exhibit failure through formation of shear bands, a phenomenon often attributed to Hadamard instability and localization of the strain into an emerging coherent structure.

Complex oscillatory yielding of model hard sphere glasses [PDF]
, 2013 The yielding behaviour of hard sphere glasses under large amplitude oscillatory shear has been studied by probing the interplay of Brownian motion and shear-induced diffusion at varying oscillation frequencies. Stress, structure and dynamics are followed

An investigation of dynamic mechanical behaviour of Ti6Al4V titanium alloy at room temperature
MATEC Web of Conferences, 2016 To study the high strain rate shear behaviour of Ti6Al4V titanium alloy, a series of dynamic compression experiments has been performed by split Hopkinson pressure bar (SHPB) using Flat Hat-shaped specimen at room temperature.

Vibrational stability of graphene under combined shear and axial strains
, 2015 We study the vibrational properties of graphene under combined shear and uniaxial tensile strain using density-functional perturbation theory. Shear strain always causes rippling instabilities with strain-dependent direction and wavelength; armchair ...
