Issued topics of Doctoral Study Program
- Advanced models of cyclic plasticity in the prediction of thermo-mechanical fatigue
The topic of doctoral thesis comes from long term focus and international cooperation in the field of cyclic plasticity and low-cycle fatigue, which will be extended by the temperature effect. Machine elements from advanced alloys allow machines operation at elevated temperatures, which brings the risk of crack initiation and leakage of hazardous medium, for example from the exhaust manifolds, turbochargers or combustion parts of turbines. The doctoral thesis will therefore focus not only to development of advanced cyclic plasticity models, but also their utilization for reliable prediction of fatigue damage and failure, which is a result of repeated plastic deformations at elevated temperatures.
- Analysis of influence of weld joint size on fatigue life of metal components
This thesis is focused on a testing sector of metallic parts welded by laser welding method. Topic is based on real application of the component in automotive industry, where is necessary to provide sufficient lifetime of the welded joint. Components in automotive are typically exposed to vibration load. Contrary to expectations, there are case where a weld with lower penetration depth value achieves a longer lifetime during vibration testing. The aim of this thesis is to analyze the dependence between the lifetime of the welded joint and the weld geometry using experimental modeling and further to use this knowledge to predict lifetime based on computational modeling.
