Coupled temperature and stress field analysis of coated components by finite element methods

Department of Material Mechanics, Modeling and Simulation

The importance of temperature and thermal induced stresses evolutions in the development of coatings.

During thermal spraying, a variety of process parameters takes influence on the final composite properties (coating adhesion, residual stresses, porosity, etc.) and on the reliability of the mechanical component. Modeling and simulation can be used for a differentiated analysis of influences and interrelations of key parameters on the process. Simulation of heat and mass transfer is an essential tool for the evaluation of residual stress formation and for a better planning of process design and torch kinematics.
