Abstract In order to study the ignition characteristic of PTFE-based reactive materials (RMs), Al/W/PTFE RMs with different W powder contents were prepared and split Hopkinson pressure bar (SHPB) test was carried out under loading conditions. The temperature rise three calculated theoretically. material model parameters formulations by using mixture equation state theory Johnson-cook model, imp...

The present study proposes an integrated prediction model for both shearing and ploughing constants the peripheral milling of Inconel 718 by using a preidentified mean normal friction coefficient. An equation is presented identification angle oblique cutting in milling. A simplified adopted obtaining shear strain tool given helix angle, radial rake honed edge radius. predicted from analytical M...

The dynamic compression deformation of 3 µm, 15 µm and 25 grain size ZK60 alloys under high-strain-rate is systematically studied. Dynamic experiments at a strain rate 1700 s−1 were conducted using split Hopkinson pressure bar, the microstructure specimen was characterized via electron backscatter diffraction transmission microscopy, as well calculation Schmid factors. results showed that alloy...

Abstract For Friction Stir Welding (FSW), several simplified FEM models have been developed to explain key parts of thermal-mechanical phenomena. In this study, simulate the FSW process AA6061-T6 aluminum alloy, a thermo-mechanical 3-D finite element model based on Coupled Eulerian-Lagrangian (CEL) approach is used. The CEL method combines benefits both Lagrangian and Eulerian approaches, allow...

On a Gleeble-3800 simulator, isothermal hot compression tests of an as-cast N06625 nickel-based alloy were conducted in wide range temperatures (950–1200 °C) and strain rates (0.1–50 s–1). Considering the influence friction adiabatic heating test, flow curves corrected. A modified Johnson-Cook, strain-compensated Arrhenius-type Hensel-Spittel constitutive models established based on corrected c...

The machining of titanium alloys poses several inherent difficulties owing to their unique mechanical properties and cutting characteristics. Finite element (FE) simulations have reduced the burden of extensive experimental trials in understanding the deformation behavior and optimize the cutting process. The FE code relies on the qualitative nature of inputs such as material flow stress model,...

An experimental test was carried out to explosively clad solution annealed Inconel 718 superalloy on quench-tempered AISI H13 hot tool steel. A wavy with vortices interface geometry was obtained from this experiment. A gradual change in the wavelength along the direction of welding was observed which was due to a change in the impact angle, following the plate contacts. In this paper, the exper...

In current industrial practice, the finite element modeling of metal cutting process is essential. this paper, analysis conventional and high-speed 7075-T6 aluminum alloy carried out. A model was developed using Johnson Cook instant on equation to investigate milling behavior under conditions. The forces in X-direction, Y-direction, Z-direction were predicted analytically for five groups differ...
