Original abstract
The main aim of this study is the estimation of the influence of point load on creep crack growth in polyethylene pipe. The linear elastic fracture mechanics approach is used and crack shape is estimated. The effect of the size of the particle causes point loading on crack shape and on the stress intensity factor value are numerically investigated. This numerical study can lead to better lifetime prediction of soil embedded pipes.

Hlavním cílem této práce je stanovení vlivu bodového zatěžování na růst creepové trhliny. K popisu pole napětí v okolí kořene trhliny je použito přístupu lineárně elastické lomové mechaniky a na základě numerického řešení je stanoven vliv velikosti částice, způsobující bodový kontat, na tvar creepové trhliny a na hodnotu součinitele intenzity napětí.
