Numerical analysis of creep crack growth experiments
Abstract
The safety analysis and the life prediction of high-temperature components with defects (flaws, cracks, ...) have to take creep crack growth into account. The C-integral (instead of the J-integral of elastic-plastic fracture mechanics) is one of the characterizing parameters to describe crack growth rates under steady creep conditions. The C-integral concept is investigated here for specimens of Alloy 800 H. (IWM)
