Modeling of temperature and residual stress fields resulting from impacting process of a molten Ni particle onto a flat substrate

Several effective numerical techniques, based on a finite element analysis, have been developed and computed independently. Results are presented describing the impacting process, and the subsequent temperature and residual stress fields of a molten nickel particle impacting onto a flat substrate. Problems of this type, especially the prediction of the thermal residual streses, are of major practical interest in thermal spray operations as a pioneering approach.[PUBLICATION ABSTRACT]
