Thermo-Mechanical Modeling and Simulation of Impact and Solidification of an Aluminum Particle

Abstract

In the thermal spray procedure described in this research, a single aluminum particle is deposited and flattened using thermomechanical modeling and simulation. The explicit software Abaqus is used to conduct the numerical analysis. In this approach, the thermomechanical characteristics of the particle and the substrate are regarded as temperature-dependent. Only heat transmission through conduction is taken into account in this investigation, and a variable thermal contact conductance is employed. To start, we compare the current model to the experimental as well as numerical data that are mentioned in the literature. During the particle impact, the evolution of temperature, displacement, Von-Mises stress, and equivalent plastic strain as functions of time are assessed. In addition, the present model that considers the thermal and mechanical interactions between the particle and the substrate has been found to assist in comprehending the mechanism of lamella formation and heat transfer during thermal spraying.
