Investigator: prof. RNDr. Ludvík Kunz, CSc.
Number of Project: IBS2041001
Agency: Grant Agency of the Academy of Sciences of the Czech Republic
Duration: 01. 01. 2000 - 31. 12. 2004

The main target of the proposed project is material research focused on problems of degradation of properties and lifetime assesment of engineerign maerials subjected to complex loading conditions. The influence of small defects and cracks on lifetime, determination of local material damage characteristics and their application for rediction of fracture behaviour of structural materials, fatigue/creep interaction and creep behaviour of advanced heat resistant engineering materials will be addressed. Thebasic research will be pointed in such a way to attain practical outputs directly applicable in applied research in trafffic and power engineering industry.
