Simulation of Cutting Parameters in the Turning of Aluminium Metal Matrix Nanocomposite Using Constitutive Models

Abstract

Abstract: The present research looks upon metal matrix composites, namely Aluminum Metal Matrix Composites (AMMCs), as well as modelling and simulation of the orthogonal metal cutting process. A fundamental component of AMMCs is aluminum alloy, which creates a percolating network and acts as the matrix stage. Multiwall nano carbon tubes are another non-metallic component used as reinforcement in the aluminum alloy matrix (CNT). Some of the primary advantages of AMMNCs over unreinforced products are higher strength, high stiffness, decreased weight, improved heat properties, controlled thermal development coefficient, and thermal/heat monitoring. The SHPB test at high stain rates is commonly used to establish the Johnson cook constants for AMMNC work piece material.The Johnson-Cook constitutive model, which estimates flow stress as the product of strain, strain rate, and temperature effects, is used to determine work hardening, strain-rate hardening, and thermal softening. FEM simulations were carried out using 2D-Deform software. When the results of the 2D-Deform software-derived flow stressandtemperature are compared to the findings of the analytical model, the results are satisfactory.
