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...

Abstract The study of solids and structures under extreme conditions often relies on simulations that employ complex material models. These, in turn, are formulated using analytical expressions depend parameters whose values need to be adjusted for optimally reproducing available experimental results and, especially, out-of-sample predictiveness. In this article we review the process required c...

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...

Classical calibration procedures for phenomenological thermo-elasto-viscoplastic constitutive models usually involve a large number of tests to identify all the material parameters, leading long experimental campaigns. In present work, novel methodology that takes full advantage full-field measurements heterogeneous test is proposed. It relies on an innovative combination Virtual Fields Method ...

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...

A new phenomenological constitutive model is proposed to predict the mechanical behaviour of thermoplastics in current research. The and method determine parameters are introduced. In model, a transition function enable smooth flow stress behaviours under both small-strain large-strain conditions. validating with testing data Polyetheretherketone (PEEK) Polycarbonate (PC), it found that this ab...

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...

Abstract Incremental sheet forming (ISF) is an emerging technology for manufacturing metal components with fewer tools and equipment compared to conventional forming. In this process, generally performed without dies punches a simple hemispherical shaped tool can be used shaping the final component. Forming limit in incremental defined by maximum formable wall angle. Finite element analysis fra...

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...
