by

Uncertainty of lifetime evaluation for cafe creep damage model Krzysztof Nowak Politechnika Krakowska, ul. Warszawska 24, 31-155 Kraków, Poland. DOI: https://doi.org/10.7494/cmms.2011.2.0349 Abstract: In the paper the influence of material microstructure randomness upon statistically observed scatter of experimental results on macroscopic level is searched through. It is well known that a lot of random factors influence … Read more

Micro- versus macro- modelling of creep damage

by

Micro- versus macro- modelling of creep damage Krzysztof Nowak Cracow University of Technology, ul. Warszawska 24, 31-155 Krakow, Poland. DOI: https://doi.org/10.7494/cmms.2009.2.0238 Abstract: In the present paper the continuous approach to model brittle-ductile transition in creep failure phenomenon is replaced by Cellular Automata (CA) model. This allows to back-up this complex phenomenon by relating it to … Read more
