Abstract:

<em>Shear strain is an indicator of degree of deformation of a material subjected to shear stress. The understanding of shear strain and shear strain rate at the primary shear zone during chip formation can be used to estimate the behaviour of materials under varying machining conditions. The aim of this study is to investigate the impact of metal cutting velocities and other cutting condition on shear strain and shear strain rate. Machining tests were conducted on a conventional lathe by varying the cutting condition at constant rake angle using <strong>Ti-6Al-4V </strong>workpiece. Restricte

Abstract:

Shear tests were performed at strain rates ranging from quasi-static (0.01 s-1) to 500 s-1 for AA7075-T6 sheet metal alloy at room temperature. A miniature sized shear specimen was used in this work to perform high strain rate shear testing. Digital image correlation (DIC) techniques were employed to measure the strains in the experiments. At maximum in-plane shear strains greater than 20%, the AA7075-T6 alloy demonstrated a reduced work hardening rate at elevated strain rates. At lower strains, the AA7075-T6 alloy showed mild positive rate sensitivity. The strain to localization (using the Ze

Abstract:

A unidirectional graphite/epoxy material was characterized at strain rates ranging from 5 × 10−6 to 5 s−1 under various hygrothermal conditions. A time-temperature-moisture equivalence principle was applied to obtain master curves for the longitudinal, transverse and in-plane shear moduli and corresponding strengths and ultimate strains of the unidirectional graphite/epoxy. It was found that, except for the longitudinal modulus which shows a slight increase with strain rate, temperature and moisture, all other longitudinal properties in general remain unchanged. All matrix dominated properties

AbstractThe generalized (Glen) flow relation for ice, involving the second invariants of the stress deviator and strain-rate tensors, is only expected to hold for isotropic polycrystalline ice. Previous single-stress experiments have shown that for the steady-state flow, which develops at large strains, the tertiary strain rate is greater than the minimum (secondary creep) value by an enhancement factor which is larger for shear than compression. Previous experiments combining shear with compression normal to the shear plane have shown that enhancement of the tertiary octahedral strain rate in

Abstract:

As the deformation of chip increases with cutting speed, the morphology of chip changes from continuous to serrated type. It is supposed that serrated chips generate due to adiabatic shear instability in the primary deformation zone. A new analytical model for predicting adiabatic shear critical condition in orthogonal cutting is proposed by considering cutting conditions and properties of workpiece material. It is found that the influence of shear strain on the onset of adiabatic shear could be neglected. The shear strain rate and temperature, however, play a leading role on the onset of adia

Machining is characterized by a large amount of localized plastic strain on material due to chip formation; hence, there is a commitment among the strain process, strain hardening, and heat softening, generating shear bands.

Abstract:

Abstract The effects of strain rate on shear bands and texture evolution of grain-oriented silicon steel were investigated by adjusting the strain rate of warm rolling. The rolling experiment was carried out at different strain rates of 30s-1, 50s-1 and 70s-1. XRD, EBSD and TEM were used to investigating the effect of the strain rate on the formation of shear bands and texture evolution. The results show that when strain rate increases during warm rolling, the texture strength of {111 }<112> deformation matrix increases at 70% and 85% reduction. The number of Goss shear bands increases,

Abstract:

Understanding the shear mechanical properties of shale reservoirs is of great significance in the study of the formation stability around horizontal shale wells and the propagation and evolution of fractures for shale fracturing. However, the existing direct shear test results are limited due to small sample sizes and low shear rates. Based on previous experimental research results, the mechanical properties of anisotropic reservoir shale in direct shear tests with different experimental conditions were explored in this study. It was found that the shear mode, shear strain rate, and normal str

Abstract:

A systematic analytical study of the mathematical properties of the nonlinear shear flow model of thixotropic viscoelastic-plastic media is continued. It takes into account the mutual influence of а deformation process and structure evolution (the kinetics of the formation and destruction of intermolecular bonds and associates of macromolecules). The model is reduced to the system of two nonlinear differential equations for the dimensionless stress and the degree of structuredness (i.e. cross-links density and so on).

Abstract:

A dynamic impact test was performed on as-rolled AZ31 alloys with gradient microstructure under various strains. The microstructural evolution and mechanical properties were systematically investigated. As the strain rate gradually increased, an increasing number of twins were formed, facilitating dynamic recrystallization (DRX), and the mechanical properties were also gradually improved. The microstructure became heterogeneous at higher strain rates, but the peak stress decreased. The impact process resulted in a significantly higher performance due to microstructural refinement, work hardeni

Abstract:

Experimental results on the high strain rate response of polycrystalline metals are reviewed, with emphasis on the behavior of pure metals. A strong increase in flow stress with increasing strain rate is reported for strain rates of approximately 105s−1 and higher. This increase is observed in pressure-shear plate impact experiments at nominally constant strain rates from 105s−1 to 106s−1. To improve understanding of the increased rate sensitivity at high strain rates, pressure-shear, strain-rate-change experiments have been conducted on OFHC copper specimens.

Abstract:

A series of multiaxial ratcheting tests were conducted on 63Sn–37Pb solder. A unified viscoplastic constitutive model was developed on the basis of the Ohno–Wang kinematic hardening model, and the rate dependence of the material was taken into consideration by introducing a viscous term. The stress-strain hysteresis loop of 63Sn–37Pb under different strain rates can be simulated reasonably well by the model. However, since the axial ratcheting strain rate of 63Sn–37Pb solder is strongly dependent on the applied shear strain rates in axial/torsional ratcheting, the original constitutive model f

Abstract:

A Kolsky torsion bar is utilized successfully in a novel rheometric experiment for measuring the transient large-strain response of polymer melts under high shear-rate loading. A molten low-density polyethylene is studied with the new technique. The results show that the high-rate shear response of the material has an instantaneous rate dependence that may not be discernible at low rates and a strain-dependent hardening that saturates at large strains instead of fading. The usefulness of the technique and the significance of the findings are discussed in comparison with a modified rubberlike l

Different stress states are imposed to the steel using purposed-designed samples. The sample geometries, including in-plane shear, dogbone and plane strain samples, are optimised by finite element modelling. Tensile tests are performed at different strain rates of 0.001 s-1, 10 s-1 and 500 s-1. Digital image correlation is used to capture the strain fields during the entire deformation process.

The damaged plasticity model for concrete was used, and the strain rate effect of concrete and steel were considered. The nonlinear dynamic response results with strain rate effect are compared with the results without strain rate effect. The distribution of strain rate can not only influence the concrete and steel, but also have some effects on the dynamic response of the high-rise reinforced concrete shear w

Fiber-reinforced polymer (FRP) composites have been widely used to strengthen the existing reinforced concrete (RC) structures to against static and dynamic loads. During the past decades, the interfacial bond behavior between FRP and the concrete substrate under static load has been systematically investigated by experimental and numerical approaches. In contrast, the interfacial bond performance under dynamic loads, e.g., impact and explosive loading, is still far away from well known, especially taking the strain rate effect into account.
