Abstract
This paper describes the research which objective is to establish the method to predict the crack initiation life of the diesel engine cylinder head caused by thermal fatigue. Both experimental and analytical researches were carried out. The experiments were to determine thermal and mechanical boundary conditions, applying a foil-type thermo-couple and a high-temperature strain gauge. FEM models for heat transfer and thermal stress analysis were prepared and refined based on the experimental results.
Finally, the authors propose a prediction method, which consists of simplified FEM analysis and evaluation of thermal fatigue strength.
