A thermo-mechanical analysis of a particle impact during thermal spraying

[Display omitted] •The impact behavior of the steel particle and substrate is investigated.•A transient thermo-mechanical model is used.•Temperature dependent material properties are used.•The effect of thermoelasticity is analyzed. The present study discusses the development of a simulation model of transient impact between a particle and a substrate. The equations for structural behavior are coupled with those of heat transfer, wherein material properties are taken as temperature dependent. The set of equations is solved with Ansys program using a direct coupling method. At first, structural model is solved without heat transfer. Then, coupled thermo-mechanical model is solved with and without thermoelastic effects. Computational results indicate that thermal consideration has significant effects on contact problem. In addition, it is shown that, themoelasticity consideration is crucial for simulating these problems to determine the structural and thermal parameters.
