Cutting force in broaching process is essential information for quality control, troubleshooting and tool life prediction, yet existing technical bottlenecks prediction acquirement internal spline holes process. Based on the mechanics of orthogonal metal cutting, a numerical model cutting constructed by Johnson–Cook material constitutive law failure taking friction both rake face flank into con...

In this study, the effects of dry, liquid coolant and LN2-based cryogenic cooling applications on cutting temperatures at 50,100,150 m/s speeds 1,2,3 μm/dev feed rate were compared in micro-milling Ti6Al4V alloy . At different parameters, internal workpiece-cutting edges (wacec) zones are simulated observed. Cryogenic cooling, dry perceived that tool wear, chip formation, strain, stresses, shea...

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...

Abstract To examine the influence of mesh density on blast loads anti-landmines (ALMs) and improvised explosive devices (IEDs) under an armored vehicle, models with different FE densities were numerically analysed. The multi-material arbitrary Lagrangian-Eulerian (MM-ALE) algorithm was used to simulate vehicle explosions. Explicit dynamic analysis performed in LS-DYNA. Blast loading simulation ...

Abstract The aim of this paper is to study the effect friction coefficient and impact angle on failure behaviors glass fiber reinforced aluminum laminates (GLARE) under low-velocity (LVI) loading. A methodology developed in commercial software ABAQUS/Explicit, its accuracy verified based results comparison between simulation experiment. In simulation, Johnson–Cook flow stress model surface-base...

A method coupling experiments and simulations, is developed to characterize the yield stress strain hardening of several metals loaded at 106 s?1 < 25 ns, typically involved during Laser Shock Peening. It was applied four materials: pure aluminum, 2024-T3 7175-T7351 aluminum alloys Ti6Al4V-ELI titanium alloy. Thin foils have been irradiated with high-power laser induce high-pressure shock wave....

This paper deals with analysis and comparison of the equivalent plastic strain temperature fields in aluminium alloy 2024 T3 (AA2024 T3) joint, macro/microstructure appearance hardness profile. In alloys hardened by heat treatment, grain size particle precipitate are functions strain, rate temperature. By analysing it is possible, to some extent, capture effect welding parameters thermo-mechani...

Abstract During the PTFE/Al reactive shaped charge jet formation, burst wave generated by explosion of explosive is sufficient to achieve ignition conditions materials (RMS). As a result, RMS will react, resulting in an energy loss from jet. In order research forming features and during liner with diameter 74 mm was prepared X-ray pulses photography experiment performed on formation. And parame...
