Strain localisation in mechanically layered rocks beneath detachment zones: insights from numerical modelling [PDF]
Solid Earth, 2013 We have designed a series of fully dynamic numerical simulations aimed at assessing how the orientation of mechanical layering in rocks controls the orientation of shear bands and the depth of penetration of strain in the footwall of detachment zones ...

Non-Newtonian Rheology of Igneous Melts at High Stresses and Strain Rates: Experimental Results for Rhyolite, Andesite, Basalt, and Nephelinite [PDF]
, 1990 The stress-strain rate relationships of four silicate melt compositions (high-silica rhyolite, andesite, tholeiitic basalt, and nephelinite) have been studied using the fiber elongation method.

Enhancing the CPT correlation with the small strain shear stiffness of sands
Ain Shams Engineering Journal, 2017 The cone penetration test (CPT) is a valuable geotechnical insitu test. Yet, the CPT correlations with the small strain shear modulus and seismic shear wave velocity still need more research to enhance their accuracy.

Strain Hardening in Graphene Foams under Shear [PDF]
ACS Omega, 2021 Strain hardening is an important issue for the design and application of materials. The strain hardening of graphene foams has been widely observed but poorly understood. Here, by adopting the coarse-grained molecular dynamics method, we systematically investigated the microscopic mechanism and influencing factors of strain hardening and related ...

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.
